Nokia will begin to implement RFID technology to their handset products. So far RFID has been applied to the goods, pet, paper money and so on.

What is RFID? It is a kind of microchip with the half size of grain sand. It works with listening for the radio query and then responds by transmitting its unique code of ID. Without battery, it uses initial radio signal as power.

Wal-Mart has used this chip for reducing the usage of bar codes and hand checking. For Nokia, this technology will much help on monitoring sales stocks and the quicker feedback on its demands.

However, the implementation still needs time for development. Not only that, the privacy laws of European Union will require that European consumers should be able to switch off this tag.
