And that's a good thing because there's not much of a future for plastic credit cards in a smartphone world. Embossed credit card numbers can be read and copied by anyone. NFC account numbers, expiration dates, and security codes are hidden from bystanders and even sales clerks. There are more secure ways to verify a user's identity using a smartphone compared to entering a four digit PIN on a checkout counter card reader. With NFC, one device can be your phone, keys, and wallet. Add a Bluetooth leash, and you'll never accidentally leave it behind. But don't think of it as a phone that stores credit card information--think of it as credit card with Web access , GPS locating, and more.
And NFC offers a bonus feature. Because NFC uses magnetic induction, the NFC antennas in gadgets can be used for wireless charging. One of Nokia's top designers has suggested that physical connectors could be eliminated on NFC phones.
NFC's tangible benefits -- secure transactions, protected device pairing, interaction with programmable tags, and wireless charging -- are fairly impressive. But often it's an intangible benefit that makes the greatest difference. Tap-and-go is likely to become one of modern life's rituals.

There is also a technology on the market now that is used for mobile authentication and is compatible with IOS, which is something that NFC is severely lacking right now. It also can be done for a fraction of the cost. Check out www.snowshoestamp.com for more information.
