-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.+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. NFC is specified in a number of ISO standards, including ISO/IEC 14443A, ISO/IEC 1443 B and FeliCa, and ISO/IEC 18092.
