Even if this year's iPhone 5 doesn't incorporate the much-hyped Near Field Communication (NFC) capabilities, a future without credit cards is pretty much guaranteed. But don't go cutting up your prized plastic just yet. A complete system overhaul is still a ways off.

NFC – the tiny chip inserted in your smartphone or smart device that allows a purchase or transaction to be made simply by waving your device near a reader – has been a hugely successful technology in some parts of Asia and, in a much more limited scope, have popped up here and there in the US and Europe. The chips can send and receive data, and if attached to your bank account will deduct payment on the go, letting you charge as you chat.
