Neat idea that is doomed to failure across certain cultures. I can potentially see people in the west getting out their smartphones and scanning QR codes instead of exchanging business cards. Still sounds a bit clunky to me. It's destined for failure in Asia where the business card is part of a corporate ritual. Business cards are passed and received in both hands as a sign of respect. They are not then shoved in your pocket but placed on the table as something of value. HiHello has a great idea here, to be able to use the camera to capture and record business card information, now that would be a useful app.
