PicturePhoning.com: Turn your phone into an interactive name badge. Instead of giving your new friend your printed business card, text them your virtual one. This action automatically places them in your online contact list and if they have a profile on contxts.com you both are connected.
The mobile badge displays a user’s name alongside a QR code that when scanned will pass along contact details. The badge also cycles through a user’s latest tweets and checkins, highlights fun facts and puts other social data on dynamic display using information from a user’s profile.
