US Mobile Market Update – Q3 2015 (Chetan Sharma)

Screen Shot 2015-11-24 at 9.55.07 AM

Check out Chetan’s latest report, US Mobile Market Update – Q3 2015. Some highlights below. More details are available at: http://chetansharma.com/connectedconsumer15.htm.

Handsets – As expected, (a) Smartphones continue to rule, with penetration in the US now at 78%! (b) On the opposite end, feature phones are becoming extinct.

Android vs. iOS: The fight for profit continues – Chetan’s report shows that Apple continues to dominate the market with 80% of the profit share, 40% of the revenue share, with only 14% of the unit share. This is in contrast to Android where its OEMs such as HTC, Sony, LG and Lenovo all lost money in their device business; if we don’t count Samsung, Android OEMs made around billion dollars (despite over $26 billion in revenues). Chetan attributes this to the difficulty in differentiating on an open platform, which I agree with.

Other – Annual household spent on Mobile data is approaching $1,000, with mobile data spend rising while landline voice has declined. In addition, cellular voice spend has also gone down. Complementing the fact above that feature phones are becoming extinct, US consumers will spend more on wearables than on feature phones in 2015. Other interesting pieces of info: number of connected devices per US household is now 5.3 with over 37% of the households in the 4-8 range, and almost 6% of the households have 15 or more connected devices.

So in summary, the US and the whole world continues its path to always connected — with the mobile device at the center of how information is retrieved and how we connect with others. The mobile device is the world’s most important social artifact, ever. Those (companies) that have not yet embraced digital and mobile, are today’s dinosaurs.

Bit.ly is not in Lybia

When deploying (mobile) apps for verticals such as Healthcare or Banking, you typically have to get the app approved or blessed by the customer’s IT security team.

Some tips or info:

  • Only deploy, even for Proof of Concepts (POCs), properly signed apps
  • Do not use or store personal identifiable information that can track users
  • Use device IDs (Advertising ID, IDFA and IDFV) that doesn’t identify individual users
  • Sensitive information shall be encrypted
  • Sensitive information shall live behind the firewall
  • Cache TTL values for sensitive data is not “infinite”
  • Show Analytics at the user aggregation level
  • Beacons do not track users. Beacons only emit the signals used for proximity and/or triangulation
  • And last but no least, if using bit.ly for whatever reason, be prepared to prove that this particular .ly domain and related servers are not at or traffic goes through Lybia — a simple traceroute will help show this point.

Improving The Patient Experience (early 2015)

Disclaimer: The French Hospital Medical Center app is powered by Phunware’s Vertical Solutions platform, one of the products that I manage at Phunware.

As the mobile lifestyle, advanced smartphones and advanced networks continue its path to convergence powering the pervasive, actionable Mobile Context, we are starting to see its impact on people’s daily lives. One such example is the impact and benefits that this brings on the user experience and the Healthcare space.

Improving the Patient Experience

Recently, the French Hospital Medical Center launched its first mobile app.

The FrenchWay
(Click link to see video via KSBY News)

“From the time that you leave your house, you’ll get a reminder and it’ll take you actually into the hospital door to the actual department you’re going to, and then after your appointment, you can continue to navigate to the pharmacy, so this really helps people have a lot less stress as they’re going through the entire healthcare journey… It’s also great for visitors as well because sometimes you may have a loved one in the hospital and trying to find them can be pretty stressful.”

This is a prime example of how the young and the old can leverage their mobile devices with its advanced features and sensors, and access to fast networks, to improve the patient experience. The key is to bring the right information at the right time, from hospital and doctor information, to information about related places, using dynamic content and notifications and location-based services such as mapping, wayfinding and navigation. Location marketing with geofences and Beacons for outdoor and/to indoor navigation and outdoor and proximity notifications brings enable for very interesting use cases and are of particular interest to Hospitals (and other verticals), as it helps patients deliver information in real-time as well as helping patients reach their destinations, all via their smartphones, improving the patient experience with the added benefit of helping reduce the costs associated with deploying such a solution as well as costs related to late or missed appointments.

Three Generations of Mobile Apps (Aug 2014)

We currently are at the third generation of native Mobile apps (2014), with each generation building upon the previous one.

The first generation was introduced to the “masses” circa 2000. This generation of mobile apps were Operator-centric and built for the first generation of mobile handheld devices such as PalmOS, J2ME, WinCE, BlackBerry OS, Nokia devices, Psion and other.

The second generation came with the iPhone and Android (2007–2008), essentially giving (re)birth to a new generation of mobile apps where rich content was king. These were apps based on advanced Smartphones and higher-speed networks that pretty much made the previous generation obsolete. During this time period the Ecosystem took center stage away from the Operator. Many of the companies behind the first generation such as Nokia, BlackBerry and Microsoft were impacted during this time period in major ways — some are gone while others and are still trying to recover.

More recently, we have entered the third generation of mobile apps where the user and user context is king, with sensors on the device and core services and infrastructure residing on the cloud.

The following table summarizes the three generations of mobile apps (2014).

On Android and Fragmentation (early 2014)

Due to its origins and philosophy with respect to openness, Android is a fragmented mobile platform. This is illustrated next:


There are different kinds of fragmentation to keep in mind.

Android platform versions. To minimize fragmentation-related headaches, decide early on what versions of Android to support. As you can see above, Gingerbread (introduced in 2011) still commands close to 20% of the Android device distribution (data above is gathered from the new Google Play Store app). It is important to keep in mind is that the more versions you support, the more testing and maintenance and related costs that you will have.

Multiple screen sizes. When creating an Android app, you will have to decide the kinds of devices to support, for example Smartphones, vs. Tablets, each with different sizes and resolutions, and provide the appropriate assets, fonts and layouts that ensures the best possible experience across such different screen characteristics. See Design Apps for Tablets (Android Developers Blog).

Hardware support. Another kind of fragmentation is related to hardware support, for example, the supported sensors and/or UI facilities. Not all devices are created equal and different device manufacturers decide what to include. A couple of examples: not all devices may support the same kind of camera, or may or not provide support for Bluetooth or for that matter, Bluetooth Low Energy (introduced with Android 4.3 (API Level 18). NFC may or not be there. Another example is the Kindle, which is based on Android 2.3 but it doesn’t provide support for many of the hardware sensors or UI facilities found on other Android devices.

Consistent UX Design. Maintaining a consistent design is not necessarily easy and can lead to a fragmentation user experience. Learn and follow the Android Design Guidelines. Google has done a great job documenting the best design guidelines for Android apps. From design principles, to styles and patterns, to building blocks, you should spend time going over these great developer resources by Google.

The good news is that as you can see on the pie-chart above, the market is consolidating on 4.x and newer and devices are getting more consistent. The whole Android reminds me of the Java Micro Edition and Sun Microsystems back then, which wanted to be open with great intentions, but that caused a lot of fragmentation and problems. The answer to this is to enforce consistency across. Google is attempting to do so by “Forcing OEMs To Certify Android Devices With A Recent OS Version If They Want Google Apps“. Let’s keep in mind that the main reason the iPhone and iOS have been so consistent with respect to platforms version, functionality and distribution, is because Apple owns the whole stack (hardware and software). But in an open platform, consistency is very hard to achieve, especially when there is competition within the ecosystem.

Using Android’s Advertising ID

My most recent piece is about Using Android’s Advertising ID (Safari Online Books blog).

The ability to identify users is important for advertising, analytics and other purposes. Android developers typically rely on the Android Device ID or Telephony IDs such as the International Mobile Equipment Identity (IMEI) to uniquely identify users, but these approaches also introduce privacy concerns. Android 4.4 Kitkat introduces a new anonymous identifier for advertising purposes. Referred to as Advertising ID, it provides a user-resettable identifier that helps protect the user’s personal identity.

On Location (and Other Sensitive) Data

Installing apps, Android in this case, is at times a bit of WTF. It shouldn’t have to, but it is. The amount of personal information that some apps gather can be extreme. This concern is especially true after Google removed the very necessary App Ops (permission manager) app.

Let me provide an example. An app that I recently installed asked for the following (and other) permissions:

Your location
precise location (GPS and network-based)

Your personal information
read your own contact card

Phone calls
read phone status and identity

Your social information
read your contacts

Your accounts
find accounts on the device

Not all apps need such amount of personal information. It is so important to gather just the information that is really needed, and nothing else. It is also very important to be responsible with things such as geo-fencing as well as having in place good privacy guidelines that are really in taken seriously.

A number of years ago I wrote a set of Guidelines for Location (and Other Sensitive) Data that that are still quite relevant. Check them out; I hope you find them useful.

shift 2020 – How Technology Will Impact Our Future

Check out Rudy De Waele’s new book project titled shift 2020 – How Technology Will Impact Our Future — a collaborative book including foresights on how technology will impact our future by some of the world’s leading experts.

See the related Kickstarter project.

The story

The idea of shift 2020 is based upon Mobile Trends 2020, a collaborative project I launched early 2010. It’s one of the highest viewed decks on Slideshare (in the Top 50 of All Time in Technology / +320k views). Reviewing the document a couple of weeks ago, I realised the future is catching up on us much faster than many of the predictions that were made. I thought it was time to ask the original contributors for an update on their original predictions and new foresights for the year 2020.

And here is Rudy!

Betting on Nokia (2013)

(Image source: http://blogs.telegraph.co.uk)

Have you given up on Nokia?

From my perspective, due to its recent (couple of years old) debacles and endeavors with MSFT, I had stayed away from Nokia.

I never believed on how their MSFT strategy was approached.

Nokia should have totally maximized their Smartphone hardware design expertise, and should have offered that to the world — running Android, Windows and their own Advanced OS. If they have done that, by just supporting the Android OS, they would have owned the other side of the marketshare (not already owned by Apple).

But instead they handed this unique opportunity, and without contest, to Samsung. Today Nokia has lost such hardware design expertise to Microsoft.

And while the world was changing, Nokia management was too comfortable. Call it arrogance or not, they assumed their leadership and marketshare would last, versus seeing it erode at such a fast rate.

Nokia failed to adopt-standardize on “touch interactions” fast enough — even though they had the technology, OS based on Symbian and R&D brain-power. Then they pulled out from Japan, then pulled out from the USA, gave up on MeeGo Phone, and sold bulk of its Qt business to Digia. Its audience, platforms, content and ecosystem was all too much, too complex, affecting company focus.

And all the above happened during the time when the Smartphone itself, the mobile ecosystem and the mobile-lifestyle in general were being redefined, by Software, by advanced interactions and beautiful interfaces, rich content, faster networks, and awesome user experiences, all which when put together led to the awesome transformation of the Mobile space as we see know it today. This is a period of 3-5 years, really the culmination of 15 years of evolution that started with pagers, feature phones, Smartphones, and now Advanced Smartphones.

Those were the early days of Mobile, which also were the days of Research in Motion (now BlackBerry) and Nokia. Because BlackBerry and Nokia where both early pioneers, is the reason why their IP portfolios today are worth billions of dollars; Nokia’s alone is worth more than $6 billion dollars. Blackberry’s IP portfolio must be very valuable as well.

There were other factors that contributed to Nokia’s demise on Mobile.

Nokia was too dependent on the Network Operators/carriers. This is to the point of sacrificing/delaying the introductions of advanced (more costly) devices into the consumer market.

Control then moved away from the network operator and into the Ecosystem — led by Apple and Google.

Back then, Nokia saw BlackBerry as a threat. They saw Apple as a thread as well, but Nokia didn’t see Android as much of a threat.

And the final straw was Nokia giving-up what is the MOST important aspect of Smartphones — the Software. And because Nokia’s software strategy was MSFT alone, it was game was over.

But past is past. Nokia has finally cut clean from MSFT, and got rid of legacy stuff. Yes, it lost lots of good people, but life goes on. The market benefits from this via new startups formed by ex-Nokians.

Nokia can now start from scratch. In many ways, it is a blessing.

So am I betting on Nokia?

Yes, I am.

Nokia is a company with lots of passion and pride. It has the smarts/people. It currently has the technologies and products that can be monetized (network, maps, etc). It owns tons of mobile and wireless intellectual property that is worth billions of dollars. And now that MSFT is buying Nokia’s device business, and is cutting clean from MSFT, Nokia is in the position to reinvent and simplify itself.

I even see how Nokia would re-enter the mobile space. If you think about it, mobile is still young; what I mean is that while the “mobile use case” has been proven, the technologies are still evolving. Yet to be invented are new approaches and use-cases related to the Mobile Lifestyle.

So I bought NOK stock and it has been going up.

(Disclaimer: I am not giving you financial advice here, just a personal perspective).

On Voice Apps (and Contextual Voice/Communications)

Future of Mobile
Image Source: The Future of the Web and Mobile (Feb 2007)

For years I have been working on mobile and related software development. This has been a world of “data”-and consumer and enterprise applications and infrastructure, that for me started in 1999-2000 with CDPD, CDMA, then GSM, 2G, 3G, and today 4G and LTE from the network side, and from the device side Symbian OS, WinCE, Palm OS, RIM, WML, HTML Basic, J2ME, and into today’s iOS and Android (Smartphone and Tablets) as the main platforms for native apps and HTML5 webapps.

More recently, I have been interested on contextual voice/communications and “Voice as an App or App Feature”.

Evolution of Mobile

Mobile has truly gone through a period of tremendous evolution and growth. Mobile is about convenience and easy access (to others and to information). The mobile Smartphone is a social artifact. And while today I believe that mobile has peaked in general (a topic for another blog), mobile has entered the phase of continuous stable growth that won’t stop — its essence will just transform into different form-factors and new interactions — all about applying the mobile context and thus improving the experience (usefulness).

The Mobile Context

The Mobile Context

“The future of personal communications and computing is the mobile handset. Part of this future is the integration with local handset capabilities and sensors and the services on the web (the cloud). Part of this future is about leveraging the hidden information found in our actions and interactions, in our surroundings, in our mobile context.”

(See The Mobile Context)

Voice has always been a fundamental piece or feature of the mobile phone, and it will always be. But in the world or era of “data”, voice has been treated as “legacy stuff”, separate and driven by its own experience, drivers, and infrastructure. Voice just works, but separate, under Operator control.

As a side note, for years, many of us have been talking about convergence with respect to mobile; an example of this is a piece I wrote back in 2007 titled the Future of the Web and Mobile that covered the expected evolution of mobile from my point of view — this was written 6 months before the iPhone was first released; looking back is pretty much on target.

The early part of the 2000 decade saw technologies, concepts and lessons-learned from Europe (Nokia), Canada (RIM), Asia and USA (Palm, MSFT, others), but their impact remained pretty much closed as well as localized to the respective regions (mainly due to Operator control). Then the years 2005-2008 were the fundamental years of transformation, and openness away from Operator control and into the Ecosystem, first in the USA (thanks to Apple and Google) which then impacted the rest of the world in big ways, into what Mobile is today. Throughout that same time-period we have been talking about the convergence with voice, but this in my opinion has never really happened. I am talking about bringing voice convergence to the next level — from the device into the App-level.

On Voice Apps

Voice is by default a multi-platform application. But the future points to voice as a dominant “mobile app”. The consumer world is massively becoming mobile, and the enterprise world will be eliminating the traditional office phones in favor of mobile. Interestingly, the effects of BYOD also impact Voice apps as well.

Even though the technologies for creating voice apps have been around for a while, today we are still kind stuck in a different world when it comes to voice: a 100+ year old world of closed voice-networks, arbitrage, peering, FCC and PSTNs regulations and other. There is a lot of history on how we got there, but for folks that come from the world of “data”, like I do, it all looks like quite a mess. Thankfully, it is an “old world” that is slowly evolving (while in the process, crashing) with the new world. I am right in the middle of this world today. One day, all of this will be completely freed from such legacy world, thanks to open IP networks, mobile, the Web, the Cloud and new business models.

Voice is slowly but surely moving into becoming a “data app” — Voice as an app or an app feature. Voice will continue to be the Smartphones *main* feature (or app). Primarily standalone. But primarily standalone with many flavors or choices beyond the “core voice support” provided by the Network Operator (for example, Google Voice). These are SIP and WebRTC clients that you can download and use, point-to-point or via the old PSTN.

Google Voice

Cloud-services companies such as Plivo and Twilio are helping with this evolution to provide Voice as an app or app-feature.

Because of the current state of “voice” as an app, depending on the “app layer” you are at, the moment you want to open your voice app to complete calls to any phone out there (that is, the PSTN), you will immediately “crash” into the legacy world of voice. This is a hardcore world of telephone numbers, activations and inventories, origination and termination and routing, agreements, and fees and regulations. To effectively deal with all of this you either have to implement all of this directly (costly), or you can use solutions on the cloud.

From the design perspective, designing mobile apps with voice functionality does require a different way of thinking from designing traditional mobile apps and web apps. The inclusion of voice as an interaction mode does require re-thinking of your application as a contextual, multi-modal app. And because voice apps is about communication, the whole thing can quickly turn into including or not other kinds of communication such as IM, SMS, video, and group-communications (conferencing), and other.


The mobile device, the Smartphone, is a social artifact — it has always been. Voice has always been the fundamental feature on these highly personal devices. But we have always been treating voice “as its own separate function”. Voice is changing. Voice as an app or app-feature with CONTEXT is coming, and is coming fast. BYOD has an impact on Voice apps that must be taken into consideration.

We are at a very interesting crosspoint where the old legacy voice world is moving into the new world of “data” and Cloud-based services and apps. The Cloud service providers to help create, manage and support such voice apps are out there, the Smartphones provide the support for native SIP stacks and libraries to write and/or include voice functionality into your app, WebRTC is coming, and you can download your own SIP clients/apps to use as well.

The future is clear: open IP networks, Mobile and Cloud-service providers are and will play an important role in the evolution of voice communications, voice as an app and the future of “Mobile”.

Dell is going Private (2013)


A month after I wrote Dell to exit global smartphone business, now I hear rumors that Dell is going private.

Many years ago I was predicting that an Asian company would buy Dell, but I wasn’t expecting Dell going private.

The Dell story kind of upset me. Dell, which is right on my “backyard”, is/was an Austin darling, used to rule the personal computing world. Today, I am not surprised of what is happening at Dell; I have been saying this for years. The Round Rock, Texas company missed the boat in a major way. You need to understand that this didn’t happen over night. It has been a slow but expected process/result — I am talking about 10 years, which is the same time-period that it took personal computing/Mobile to evolve into what it is right at this moment — just look around and you know what I am talking about: Smartphones, Tablets, personal information devices. This mess all started during the days of Kevin Rollings.

For Dell, Mobile always meant laptops. The company wasn’t able to understand that personal computing was transforming, right in front of their eyes, into the new form of Tablets and Smartphones. Actually, some inside the company did, and they created prototypes and Tablets and Smartphones *but* without a proper business-plan and without proper vision. They thought they were in control, but they weren’t. Then, they couldn’t adapt fast-enough. They couldn’t make it happen; didn’t know how-to. Technology leadership requires vision and investing in R&D — Dell didn’t do either. Then Apple and Google-and its partners all ate Dell’s lunch. It wasn’t a tech problem, but a total lack of vision — a business (management) problem. Shame on you Dell management.

Rumors say that Microsoft would invest $2 billion on the deal. Good money — but Dell would once again miss to identify root causes. Dell needs to understand that part of the reason it has failed and is failing is truly related to its dependency on Microsoft for all things Software. Dell needs to realize and learn that Software is where differentiation comes from. Software runs the world. It must take ownership and leadership both on software and hardware.

It is no surprise why both Dell and Microsoft missed the personal computing boat — the mobile opportunity. It is a problem with the way of thinking and lack of vision (that is, lack of proper leadership).

As I wrote recently, moving forward, Services and Cloud is perhaps what Dell should focus on, and forget about the rest. The problem is that Dell’s dependency on PC revenue is still at 70%; it is a tough problem to solve.

The new personal computing (aka Mobile) is perhaps too late for Dell at this point. But with the right leadership, anything can happen. If Dell insists on addressing the personal computing market, it must do a re-boot, and bring totally new minds (business and tech) into the equation — something they should be able to do now if they go Private.

Total Time Spend Using Mobile Web vs. Apps (October 2012)

Saw this today at BI website…

Source: Business Intelligence (BI)

Source: Apps More And More Important Than The Mobile Web (Business Intelligence). Original report by Nielsen.

The above is self-explanatory…

What I find ‘funny’ is that over time I have noticed that Business Intelligence’s opinion on “native vs. web on mobile” swings back-and-forth (based on the top news of the day). In this particular case, all the recent attention to “native vs. mobile web” is thanks to Mr. Zuckerberg.

The Eternal Debate — MoMo London Event on HTML5 v.s. Native (Sept 2012)

Native vs. Web
Image Source: Mobile App Testing Blog

Seems that I missed a very good debate. I just read a blog on MoMo London event on HTML5 v.s. Native.

Seems like an eternal debate.

Today in 2012, I am still amazed we still are debating this and have not been able to address this. This is really a ~10 year old debate, still driven by the exact same issues and pros/cons as before — centralized vs. not, cross-platform vs. not, maintainability and fragmentation, code-reusability or not, better user experience vs. not, performance, security, access to device APIs vs. not, thin vs. thick, app discovery, etc. etc. etc.

We can argue the basics are here (HTML5, CSS3 and JS-and-related frameworks), but creating great mobile webapps with great user experiences is today only possible by a few; in other words, is a niche area. (Not even Facebook was able to pull it off, right?).

The day the “common mobile developer” is able to create great mobile webapps with ease, is the day this debate will end.

Today still, “user experience” (driven by network latency, app richness, toolsets, adoption by big brands) is best maximized on mobile native. Today still we have to talk about classes of mobile applications (again driven by network, richness, performance, storage, toolsets, maintainability, security, cost of one vs. other, etc) — then decide what is better suited — native vs. web on mobile.

How much longer will it take settle out this debate? 3 years? 5 years? 10 years? Right now I say around five years — I wish I am wrong. But does it really matter?

In the meantime, successful mobile developers redefine the meaning of “full stack developers”; successful mobile developers must be “End-to-end, Cross-platform, Full Stack Developers” — this is a lot of complex ground to cover.

Related to this see “The biggest mistake we made as a company was not investing enough on native.” — Zuckerberg (2012).

Android Platform Versions (2012)

Below is a snapshot of the Android platform distribution, as of September 2012.

Android Platforms Sept 2012

As you can see, the majority of the devices out there, close to 60%, are still 2.3 (Gingerbread). This is followed by ICS with close to 21%. Froyo 2.2 is 14%.

I hope that by March (but more likely, summertime or later) of 2013, that by then the majority of the Android devices out there are 4.0+. This would make the Android app developer’s life in general much simpler — by (1) minimizing the number of major Android platforms to deal with, and (2) making it easier/cheaper to implement (or move up to) the recommended Android design guidelines. The result of this includes (1) cheaper to develop/maintain apps, (2) consistent apps per developer, and (3) consistent look/feel/behavior across the app market.

For this to happen, device manufacturers and operators must help transform the above piechart to be mostly 4.0+ Android devices. They can help by literally selling less (and even better, stop selling) Gingerbread/2.3 and older devices. If you look around you will see that operators are still selling Gingerbread devices. And we need Google to have more cojones with respect to this and stimulate, if you will, both the device manufacturers and operators to move forward — this transition is taking forever! (Note: Gingerbread was introduced on December 6, 2010.)

Some customers may leave feedback as “why the app does not follow the Android UI guidelines”, or “why the app doesn’t support the ICS UI paradigm” — but again, 4.0+ is just a smaller fraction of what is out there!

In the meantime, there is the Android Support (Compatibility) library. Also, see Backwards Compatibility (Android Design Patterns).

“The biggest mistake we made as a company was not investing enough on native.” — Zuckerberg (2012)

The title of this blog is not what Zuckerberg actually said, but is what he really meant.

From TechCrunch Disrupt — Zuckerberg Shows He’s The Right Man For The Job:

“The biggest mistake we made as a company was betting too much on HTML5.” While building native apps that were bacially just a wrapper for the mobile web standard let it experiment quickly, it made the apps run way too slow. “We burnt two years.”

This validates what I have been saying for years… Don’t take me wrong, I’m a fan, user and developer of webapps. Web on mobile is big and the mobile browsers and frameworks are getting so advanced, and the mobile webapps so kickass, but for certain kinds of apps, especially rich consumer-based applications, native is the way to go today.

Consumers are about great user experiences and great quality. The “mistake” Zuckerberg refers to is not really that they bet “too much” on HTML5, but that they didn’t invest enough on native.

But that said, FB has nailed it down; recognizing the need to invest on the native apps and related infrastructure, and focusing on mobile first.

Any company going global must have a mobile first strategy — we know that for many around the world, their online experience will be on mobile.

Starbucks App == Mobile + Convenience

The Starbucks App for Android 2.0 is out on Google Play (see announcement on VentureBeat).

Good to see…

(I was one of the people who contributed design & dev to this product, specifically the Card Management tab/functionality, plus some other.)

Starbucks have proven, starting with their iOS app, that consumers are ready for mobile payments — as of April 2012, Starbucks apps have done over 42M mobile payment transactions (see announcement on VentureBeat).


Convenience is always a big winner. In the case of Starbucks it is about payments, rewards and store information right on the palm of your hands.

There is another important aspect here. It also shows that stores must have the whole infrastructure in place to be successful:

  1. The POS that are enabled with the appropriate readers and software,
  2. The devices/smartphones with the SW and functions (the apps), and,
  3. The scalable service infrastructure with the appropriate back-end integrations, and the right kind of services-and content — in the case of Starbucks, authentication, payments, rewards, store information and related-integrations.

It is then that users will adopt this in masses; and, yes, it is about convenience.

(Card management tab with Pay Now, and embedded PayPal Integration for Card Reload)

Digital cards are at the center of the app. The app, which is global-ready, allows smartphone-users to load the digital cards (dollars, pounds, etc, depending on country) via credit cards and/or PayPal — all within the app, thus maximizing the user experience. The digital cards are then scanned at the stores. For this, the app uses 2D-barcodes that are scanned/read by the POS using regular barcode scanners, consummating the transaction.

Looking forward, this app is a good candidate for NFC and/or other proximity-based technologies. If the NFC infrastructure was in place, that is, the readers and the NFC-capable smartphones, I will bet that it would also be a winner. But full, pervasive NFC deployments are still are a few years away, delaying its adoption. As a result, today, 2D-barcodes is the way to go.

(This is not real, just a concept scenario that I put together for the Starbucks app with NFC support)

As mobile app designers, the important thing is to design your application in a way that 2D-barcodes or NFC or other are just interaction channels — the key is keeping the rest of the app- and related supporting infrastructure (servers, authentication, exposed services, payment infrastructure and so on) properly abstracted. As a side note, this is a reason why Square is ready for the future — it has all the infrastructure in place, and today their reader is the Square-reader, and tomorrow it can be something else. Starbucks is ready too.

Security & Privacy on Mobile Apps, Part 3 – PCI Compliance

This is Part 3 of a series on Security & Privacy for Mobile Apps.

Part 1 of this series introduced main concepts related to security on mobile apps. Part 2 went deeper into the security elements and guidelines related to security and privacy on mobile applications. In this Part 3, I will cover security from the PCI compliance perspective.

Handling Personal or Sensitive Information

Personal and sensitive information include any information that is critical for a user, for example credit card numbers, credit card validation codes, social security numbers, driver’s license numbers, name, addresses and date of birth, and other Personally Identifiable Information (PII). Any such information must be properly handled and secured.

When dealing with credit cards in particular, you may have to adhere to strict security requirements such as the ones as defined by the Payment Card Industry Security Standards Council, or PCI for short. The PCI council defined a number of requirements and certification to help to ensure both devices and software applications all take the proper steps to protect cardholder data. The PCI council consists of the following companies: American Express, Discover Financial Services, JCB International, MasterCard Worldwide and Visa Inc.

Even if your application is not handling cardholder information, the requirements by the PCI council are good guidelines to follow if your mobile (web) application deals with personal sensitive information of any kind.

PCI Data Security Standard (DSS) requirements

Let’s take a look at the PCI Data Security Standard (DSS) requirements. These requirements apply to “any entity that stores, processes, and/or transmits cardholder data.” In short, “if your business accepts or processes payment cards, it must comply with the PCI DSS.” Note that “to comply”, means that the payment application must pass a PCI-provided assessment.

Table 1: Payment Application DSS Requirement

   Source: Payment Card Industry Security Standards

The PCI Data Security Standard defines fourteen (14) requirements — some technical while other operational — that affect both the server-side and client/mobile-side of the payment application. Let’s cover each of these requirements in some more detail:

1. Do not retain full magnetic stripe, card validation code or value or PIN block data

How to: Always prompt for such information; never store locally on the device. Always prompt for PIN.

2. Provide secure password features

How to: Always prompt for PIN before allowing access to the app’s critical paths or sensitive information. Use the PIN to secure application data.

3. Protect stored cardholder data

How to: Do not store cardholder information on the device. Tokenize access to critical information (tokens are covered below). Use the PIN to secure application data.

4. Log application activity

How to: Keep a local log of critical activities, such as when user logs into the application, performs a purchase, and so on. This typically is a circular log. Provide the means to remotely access or upload the log as needed.

5. Develop secure applications

How to: Design and implement the mobile application with security in mind. Do this by implementing the different requirements being discussed in this article.

6. Protect wireless transmissions

How to: Perform all communication over an encrypted secure connection (typically over HTTPS/TLS).

7. Test applications to address vulnerabilities

How to: Implement a robust test-suite that includes automated and manual testing that validates that no access to critical application paths is possible unless the user authorizes it via a PIN, that API calls and data over network connections is in fact being encrypted, that no credit card information is stored locally, and that any personal information stored in local data is properly encrypted.

8. Facilitate secure network implementation

How to: See #6 above

9. Do not store cardholder data on a server connected to the Internet

How to: Design a network architecture that separates production systems from the public Internet. Deploy production servers with critical/personal information behind a firewall.

10. Facilitate secure remote software updates

How to: Only trust software updates from trusted sources. Leverage app stores/markets and app signing for native applications. Leverage centralized approach of mobile web apps. Perform all software updates over a secure network connection.

11. Facilitate secure remote access to application

How to: See #10. In addition, see #6 — all remote/network communication shall only be done over secure network connections.

12. Encrypt sensitive traffic over public networks

How to: See #6 above

13. Encrypt all non-console administrative access

How to: See #4 and #6 and #10. All access to secure data, administrative or not, shall be done over secure connections.

14. Maintain instructional docs and training programs for customers, resellers and integrators

How to: From the mobile application perspective, provide FAQ and Help pages that describe the privacy and security aspects of the application. Include Privacy terms and conditions.

Other PCI Information and/or Requirements

The following two tables show the general PCI goals vs. requirements, and PIN-entry device security requirements.

Table 2: PCI Data Security Standard (DSS) requirements

   Source: Payment Card Industry Security Standards

Note that most of these requirements on Table 2 were covered on the previous section.

Table 3: PCI PIN Entry Device Security Requirements

   Source: Payment Card Industry Security Standards

And these requirements on Table 3 are related to physical devices, in particular device characteristics and management requirements.


On this 3-part series we have covered security on mobile applications – introduction, elements and guidelines for secure mobile apps, and PCI requirements for mobile payment applications. At the end, it is about protecting the user by protecting related critical information –credit card numbers, credit card validation codes, social security numbers, driver’s license numbers, name, addresses and date of birth, and other Personally Identifiable Information (PII); all such information must be properly handled and secured.

As privacy continues to become more critical over time, with the number of apps exponentially increasing, and with potential legislation in the future, having clear privacy and security implementation, wording/messaging and responsibilities are all very important.

Finally, as product owners and developers, we are all responsible for properly implementing our mobile applications and protecting the user…

On Mobile Industry Numbers and Mobile Jobs

The other day I tweeted this:

(URL: https://twitter.com/eortiz/status/223096404233564160)

Then I read at the Royal Pingdom blog some interesting Internet 2011 in numbers; looking at the mobile-related numbers, we have:

Mobile (July 2012)

  • 1.2 billion – The number of active mobile broadband subscriptions worldwide in 2011.
  • 5.9 billion – The estimated number of mobile subscriptions worldwide in 2011.
  • 85% – Percentage of handsets shipped globally in 2011 that included a web browser.
  • 88% – Apple iPad’s share of global tablet web traffic in December.

    So the mobile space is a pretty hot space indeed. Let’s now look at some mobile-related job salary numbers, courtesy of Indeed Salary; note these are *average* salaries:

    Mobile Architect

    Mobile Developers

    Mobile Designer

    Mobile Web Developer

    Android Developer

    iOS Developer

    Windows Mobile Developer

    BlackBerry Developer

    Symbian OS Developer

    Mobile Product Manager

    I actually find this quite low for Mobile Product Managers.

    Mobile Project Manager

    Let’s now look at some trends, courtesy of Indeed Trends. Interesting is how it starts to trend up towards the end of 2010 for all the top mobile OS platforms –iOS, Android, HTML5:

    iOS Job Trends

    HTML5 Job Trends

    Android Job Trends

    Mobile-app Job Trends

    Symbian OS Job Trends

    Note the roller-coaster trend for Symbian OS…

    Security & Privacy on Mobile Apps, Part 1 – Introduction

    This is Part 1 of a series on Security & Privacy for Mobile Apps.

    (Note: in this article mobile apps means both native and webapps)

    Are you Serious About Security on your mobile apps or webapps?

    Security and privacy is an area that too often is not being properly addressed on mobile apps in general. From the product requirements, to the design and implementation of the mobile app, properly securing sensitive information means addressing this end-to-end: on the device/smartphone, through the network, and on the servers on the cloud.

    Examples of sensitive information:

    • Personal Identifiable Information (PII)
    • Cardholder and other credit card information
    • Health/medical information
    • Tracking users/geo-location

    And it is not only about collecting or not sensitive information, but also about 1) preventing others from gaining access to the sensitive data collected by your app, and 2) how to communicate to the user about how the app itself deals with such sensitive data.

    As product owners and developers, we all should follow proper security and privacy guidelines, regardless of the kind of application. But when dealing with critical or sensitive information, we must go beyond guidelines and treat privacy and security as application requirements.

    Increase in Apps with privacy & security requirements

    Developers do need to be serious about security and privacy on their mobile apps:

    But many developers find addressing privacy/security as challenging:

    Why the need to be explicit about security and privacy?

    Addressing security/privacy goes beyond protecting and securing data. It is a fact that security/privacy on mobile apps can quickly become confusing. And this impacts how we tell the users about what the application does with sensitive data. Typically this communication is done via privacy terms and/or policies that are hundreds of lines long and hard to read on a mobile device, thus many people simply skip reading it.

    Simplifying privacy communication — a case for “Classifying Apps”?

    Imagine that we can abstract and simplify how we communicate to the users the matters related to privacy/security. And idea is on classifying the Apps based on how they handle sensitive data, for example:

    • Class A — Collects data
    • Class B — Stores data
    • Class C — Shares data
    • Class D — Tracks the user
    • Any other?

    Regardless, think about these classes when designing your application, and crafting your privacy policy documents.

    Now imagine that these classifications are standardized, and with this, the Privacy wording for each these classes of apps is standardized as well — all with the goal of making such wording very clear and easy to understand, standard, and referenceable — similar in idea to how licenses such as GPL, MIT, Apache have been defined, standardized and used all around.

    With such “standardization”, mobile apps would have a very clean, simple privacy policy that is familiar in wording and meaning, for example:

    Privacy Policy — this application:

    1. Collects Data
    2. Shares data
    3. Tracks the user

    Please click on the appropriate hyperlink for more information.

    I would seeing an initiative of some kind to do just this (I’m investigating this as we speak). If you have any thoughts, please drop me a line. Perhaps there is something out there already that I haven’t seen yet. If there is nothing there yet, I believe it is worth it to follow up on this and come up with simple, consistent, familiar privacy messaging (and badge?) across platforms and applications.


    Personal and sensitive information include any information that is critical for a user, for example credit card numbers, credit card validation codes, social security numbers, driver’s license numbers, name, addresses and date of birth, and other Personally Identifiable Information (PII). Any such information must be properly handled and secured.

    As privacy continues to become more critical over time, with the number of apps exponentially increasing, and with potential legislation in the future, having clear privacy and security wording/messaging and responsibilities is very important. And as product owners and developers, you/we are responsible!
