NFC-enabled (near field communication technology)

Leading up to the release of what turned out to be the iPhone 4S, rumor had it that Apple may have been working on integrating near field communication technology (NFC) into the next iPhone. This is sort of a bar code replacement technology that would allow your iPhone -- among other things -- to act as a payment device (e-wallet) or even a car key.

Since the feature isn't in the iPhone 4S, the odds increase that it'll make it into the iPhone 5.

Chances of implementation: 40 percent
