I am still not sure you know what QR codes are, they are images which can be
printed on visual media and displayed on any visual media from newspaper to cell
phone. NFC is a complex EM protocol requiring a lot more hardware to handle. I
somehow can't imagine NFC coupons in my (paper) junk mail, magazines, etc.
NFC supposedly will compete with credit cards, but I'm really doubtful about how
I would send NFC to or from a vendor for mail order, so I think the niche is
quick pay like the Mobil swipe key fob.
We might see QR replacing bar codes, but I'm not sure there's really an
advantage there, either. For login, they are pretty easy to copy, so might be
less secure than swipe cars or RFID devices. Good if generated by a one time
