NFC (Near field communication)
Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication
with each other by touching them together or bringing them into close proximity, usually no more than a few centimetres.
Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex
communications such as Wi-Fi. Communication is also possible between an NFC device and an unpowered NFC chip, called
a "tag".
