Near Field Communication Technology or NFC jointly developed by Sony and Philips 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 Philips form NFC-forum 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.
A patent licensing program for NFC is currently under development by Via Licensing Corporation.
[edit] Essential specifications
- Works by magnetic field induction. It operates within the globally available and unregulated RF band of 13.56 MHz.
- Working distance: 0-20 centimeters
- Speed: 106 kbit/s, 212 kbit/s or 424 kbit/s
- Passive Communication Mode: The Initiator device provides a carrier field and the target device answers by modulating existing field. In this mode, the Target device may draw its operating power from the Initator-provided electro-magnetic field.
- Active Communication Mode: Both, Initiator and Target device communicate by generating their own field. In this mode, both devices typically need to have a power supply.
- NFC can be used to configure and initiate other wireless network connections such as Bluetooth or WiFi
