Stamkey is a PC/mobile application that allows you to embed information in a 2D tag called a QR code — essentially a bar code that encodes information in both the x and y axes instead of along the usual unidirectional strip. The Stamkey stamp is then readable by a cameraphone, enabling transmission of the encoded data into your phone. If you haven't already guessed by now, Stamkey is a Japanese innovation, and users in that country are placing the QR codes on business cards for immediate transfer of contact information. While we would rather just cut out the analog middleman altogether and have our phones beam contact info to one another, we can see some interesting possibilities in the idea — suck down a set of text directions to a club from a concert poster, perhaps?
