NFC stands for Near-Field Communication and is a set of standards (established in 2004) for small, portable devices to establish radio communications with each other. Devices need to be close, usually no more than a few centimeters apart (and often they need to touch), which is why it's a Near-Field way to communicate. The standards cover data exchange formats defined by the NFC Forum (no, not that kind of forum) and are based on the original radio frequency identification (RFID) standards. The forum also certifies devices like tags, cards, and smartphones.
Uses of NFC:
- Matching encrypted security code and transporting access key;
- Due to short transmission range, NFC-based transactions are possibly secure;
- Instant payments and coupon delivery using your handset, as we do with your credit card or debit card;
- Exchange of information such as schedules, maps, business card and coupon delivery in a few hundred milliseconds;
- Pay for items just by waving your phone over the NFC capable devices
- Transferring images, posters for displaying and printing
NFC can be used in social networking situations, such as sharing contacts, photos, videos or files ,and entering multiplayer mobile games.
