The QR code is set to be the "cassette tape" of accessing information in my opinion. NFC or another-thing-yet-to-come may become the best way of telling my "hitchhikers guide" which bit of the "Deep Thought" database it needs to access via a higgs boson hyperspace wormhole...... but when that doesn't work, or isn't supported by system XX, or it has been superseded by upgrade EEE .... then it will be the QR code that still works. By all means build your stuff to handle NFC (we are) - but one of the problems with NFC is that there is no symbol of where to swipe it. I think our users will work out that the NFC chip is behind the QR code. Because despite the predictions .... your average Jo knows what a QR code is for.
