Near field communications or NFC is one of the emerging wireless technology. A NFC tag can contain small amounts of information such as URL/web address as well as numerical and textual data. It is composed of a microchip attached on an antenna. The microchip contains the stored data and it can transfer this to another device such as a mobile device or mobile phone. The transfer is only initiated when the receiving device is in close proximity with the tag, usually about 3-4cm.
