 +=====  Summary  =====
 +See also: [[sensors:radio_frequency_identification|Radio Frequency Identification (RFID)]]
 +====  Introduction  ====
 +Near-field communication (NFC) allows two devices to communicate within 4cm using short-range radio on the 13.56MHz band. NFC shares some of its technology stack with [[sensors:radio_frequency_identification|Radio Frequency Identification (RFID)]], though it is a newer technology with more features, most notably the ability to write as well as read data.
 +
 +NFC is specified in a number of ISO standards, including ISO/IEC 14443A, ISO/IEC 1443 B and FeliCa, and ISO/IEC 18092.
 +
 +While RFID is a read-only technology, NFC allows for two-way communication between the NFC "tag" being read and the NFC reader. Common uses include contactless payment, smart cards, door access fobs, attendance tracking, and more.
