While I am all for NFC, it kind of scares me. Only because, I can say with absolute certainty, that most people have no idea how to even use a credit card. Still. And as old as the credit card is it is still the easiest thing to fake and commit fraud with. I see it daily. What's worse is, the credit card should be the safest form of payment, and it absolutely is the easiest way to protect your own purchases- but people still don't get it. Credit card fraud is a gold mine, and it's the consumers fault virtually every time. Tech that old should be more stable than it is, but it gets easier to fraud by the day. They say the con man is always one step ahead of you, but in the case of credit cards it's more like a hundred steps- I don't know if that would improve any or not with widespread roll out of NFC.
I have no beef with NFC, I'd likely use it to pay for things. I find it's other uses more interesting though. I'm using a Lumia 920 right now and I was kind of bummed when I saw how restricted the NFC functions are. My next phone will probably be the Galaxy S4 and maybe that will have some more options.
