iphone-qrcode

QRCodes are two dimensional bar codes very popular in Japan. This app is a QR Code reader which uses the iPhone camera. Currently, the app works with codes from semapedia and my own generated codes. I'm having some bugs in certain conditions ... [More] which I think center around retries. (for a 3-Q code, it tries 3-Q first, then 3-H repeatedly which is wrong). Also, it doesn't actually decode the data yet to figure out if it's a URL. That'll be easy. :) [Less]
