Do you realize that the average person doesn't even know what a qr code is?
Most of us here are tech people or at least a bit in tune . The vast majority, not so much.
You see how the masses think apple created nfc while it's been around for years. People are going to love that qr system. I'm not one of them, but I'd put money in it doing pretty good.
QR codes have ready had their chance with the huge marketing blitz, what, 2 years ago? The average consumer knows what they are and they are not using them, which is why it's a dead system. I'm not saying Apple has the answer, but they are making it really easy to use in a way that no one before them has.
