Near-field communications, or NFC, is a short-range, contactless technology that enables wireless transactions. The technology typically requires a distance of 4 cm or less, and can be embedded within the SIM card or actual hardware of a mobile phone. NFC technology can also be contained on tags, key fobs or stickers.
The primary use case for NFC is mobile payments, but it is also being used for coupons, mobile loyalty programs, remote access, data collection and exchange, and transportation, and in industry verticals like health care.
NFC is approved as both a International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC) and Ecma International standard.
