It may not be the first time we've heard about Apple considering Near Field Communication (NFC) for a future iPhone, and it won't be the last. The technology has the potential to make paying for things as easy as passing your device near a wireless NFC cash register. Patently Apple has uncovered a recent NFC patent filed by the company in December 2011.
The premise of the patent is that iPhone owners could use NFC technology to easily share music with their friends or family. The process would work by allowing the user to wirelessly send a gift such as a song to a nearby iPhone. Sharing from the iTunes playlist would cost money, which would then be deducted from the gift giver's account.
