What is NFC

Near field communication, or NFC, is a set of short-range wireless technologies, typically requiring a distance of 4 cm or less.
NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target. This enables NFC targets to take very simple form factors such as tags, stickers, key fobs, or cards that do not require batteries.
Up to now there are some phone that inside have NFC tag.
