- Exchange data between devices directly. At the moment, peer-to-peer communication between devices is complicated: They usually need to be connected to the internet etc. With NFC, you will be able to tap one device onto another to initiate a data exchange. Let’s hope that all operating systems will support a common standard for such exchanges. Quoting the Wikipedia article on NFC:
NFC offers a low-speed connection with extremely simple setup, and could be used to bootstrap more capable wireless connections. It could, for example, replace the pairing step of establishing Bluetooth connections or the configuration of Wi-Fi networks.Wi-Fi Direct  should work just as well as Bluetooth in peer-to-peer scenarios, while giving you more bandwidth.

It will happen eventually, but rumors are increasing that the next iPhone will support Near Field Communication (NFC). NFC would enable the following features:
