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 NFC (near-field communication) technology into the next iPhone. This is sort of a bar code replacement technology that would enable your iPhone 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. Also, the newly announced iOS 6 Passbook feature, which lets users store and quickly access electronic versions of all their tickets, boarding passes, and merchant cards in one place, may indicate that NFC will be added to the next iPhone.

Chances of implementation: 50 percent
