Presentation on QR Codes
I stumbled across this presentation about QR codes and their uses, specifically their uses in libraries and museums. I'm a sucker for the prezi.com style of presentation animation (ooh eye candy :) ).
In the "drawbacks" part of the presentation, it mentions that these codes require special applications. I was trying to address this exact shortcoming with snapmyinfo by creating alternate ways of decoding without specialized applications. Contact sharing was a good first target, but if there is interest, I still plan on opening up the email decoder to decode all QR codes.
