Apple loves QR codes -- you've only got to look on the intimate parts of its products to know that. Thanks to a supposedly leaked test report image, left on a iPhone 5 shipped directly from China, this love for QR codes extends to manufacturing as well. That "Fail" message is a bit worrying -- not the kind of thing you'd want to see on your shiny new iPhone 5.
If Apple's been using QR codes reliably in testing on screen, and I'm assuming it has been for a while now because of the black bars at the top and bottom of the screenshot -- a hang over from pre-elongated iPhone 5 days -- it's no wonder Cupertino plonked for them for Passbook over NFC (even if we see it as a bit of a step backwards).
I can't say I'm that enamoured with Passbook just yet; there are only four ticket apps for it in the UK store, and none of them seem particularly useful. It might come in handy next time you take a flight or something, I guess. Plus you can get it on Android too, so it's cross-platform, kinda. [AppleInsider]
