The next big thing is Touch.
Touch is the next Click!

Touch for payments, using your mobile handset. Touch for learning about your surroundings. Touch for exchanging information. Touch for associating (connecting) the physical and the digital worlds.
I believe NFC will be as pervasive as Bluetooth is today — but we are three to five years away.
I’ve created a Touch/NFC page here in this weblog (see tab above), dedicated to covering Touch, NFC and related.
