Near Field Communication

From Academic Kids

Near Field Communication Technology or NFC jointly developed by Sony and Phillips was approved as an ISO/IEC standard on December 8 2003. It was approved as an ECMA standard earlier on.

On March 18, 2004 Nokia, Sony and Phillips form NFC-forum (http://www.nfc-forum.org/) to advance NFC development.

Near Field Communication Technology holds the promise of bringing true mobility to consumer electronics in an intuitive and psychologically comfortable way since the devices can hand-shake only when brought literally into touching distance.

Essential specifications

  • Works by magnetic field induction
  • Maximum working distance: approx. 10cm
  • Speed: 106 kbit/s, 212 kbit/s or 424 kbit/s
  • One-way (Passive) or Two-way (Active) communication
  • NFC can be used to configure and initiate other wireless network connections such as Bluetooth or WiFi

New specifications

In addition to the original modes of Active (bidirectional) and Passive (one-way) communications it is now apparent that they have introduced a third mode of operation: Transponder. In this mode, the tag gets its power from the other device, so that tags without batteries or electric grid access can communicate information when an NFC device with power is brought into range [1] (http://digital-lifestyles.info/display_page.asp?section=distribution&id=1744)
