"It's a URL, but just one used to open an app with some data. E.g.: http://iosdevelopertips.com/cocoa/launching-your-own-applica..." http://iosdevelopertips.com/cocoa/launching-your-own-applica... OK, but presumably a very long URL with a lot of hasing/coding in the URL that not only describes the transaction but secures it, correct ? QR Codes are an open-standard - they are not something that wechat made up - so could you use some other mechanism to transmit that URL ? Could I email the very same URL and expect it to work ?
