Near Field Communication or NFC is a short-range high frequency wireless communication technology which enables the exchange of data between devices over about a 10 centimeter distance. The technology is a simple extension of the ISO 14443 RFID proximity-card standard that combines the interface of a smartcard and a reader into a single device. An NFC device can communicate with both existing ISO 14443 smartcards and readers, as well as with other NFC devices, and is thereby compatible with existing contactless infrastructure already in use for public transportation, access control and payment applications. NFC is primarily aimed at usage in mobile phones. Simply said, mobile phone equipped with NFC technology can work as a chip card and at the same also as an RFID reader. This function creates of course great possibilities for number of applications like mobile ticketing, smart poster, etc. More information about NFC can be found on www.nfc-forum.org.
