Near Field Communication (NFC)

A form of very short range wireless communications is needed for many applications. NFC is a set of protocols that enable two devices to establish communication by bringing them within 4 cm of each other. It is distinct from other wireless technologies:

  • Bluetooth: Bluetooth has been designed to transfer data over much greater distances, whereas NFC is designed to be close proximity.

  • Wi-Fi/IEEE 802.11: Wi-Fi is designed for local area networks, and is not a short range peer to peer technology.

Each full NFC device can work in three modes:
Review: Near Field Communication (NFC)
    Which statement is NOT true about Near Field Communication (NFC)?

      Bluetooth has been designed to transfer data over much greater distances, whereas NFC is designed to be close proximity.
      CDMA (Code Division Multiple Access) is designed for local area networks, whereas NFC could be a short-range peer-to-peer technology.
      NFC is a set of protocols that enable two devices to establish communication by bringing them within 4 cm of each other.
      RFID (Radio-Frequency Identification) is a much broader technology, whereas NFC is a specific case which is defined by standards enabling it to be interoperable.
