love the digital wallet idea.
I suspect NFC (Near Field Communication) technology in mobile phones will start to replace bank cards etc.
Its already being using in Japan. We demonstrated a prototype Nissan Juke to Renault/Nissan at the end of last year that used NFC in a mobile, basically acting as a key. (also charged the phone)
So not sure we would still be carrying aroung seperate bank cards etc..
