Near Field Communication (NFC) is a short-range wireless connectivity standard that allows devices placed within a few centimeters of each other to exchange data. The NFC standard enables two communicating devices to read and write to each other allowing transfer of information such as contacts, links, or photos.  

NFC also allows one-way communication, where an NFC powered device (such as a phone, credit card reader, or commuter card terminal) reads and writes to an NFC-chip. This, for example, enables NFC-chip embedded cards to be used for payments at NFC terminals.
