What is NFC - Near Field Communication?
It is a short range wireless RFID technology that makes use of interacting electromagnetic radio fields instead of the typical direct radio transmissions used by technologies such as Bluetooth.
It is meant for applications where a physical touch, or close to it, is required in order to maintain security. NFC is planned for use in mobile phones for, among other things, payment, in conjunction with an electronic wallet, and for setting up connections between Bluetooth devices (rendering the current manual Bluetooth pairing process obsolete). The technology is promoted by the NFC-Forum.
Simply said, it is the use of the cell phone as we now use our credit cards. The techonology does not seem to find it break through yet, but maybe as the use of smart phones are exploding, we will see credit card companies will take the lead?
