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 key, though. -- Bill Davidsen <davidsen@xxxxxxx> "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
