RFID

RFID is a bar code like technology that allows for data to be transmitted from an RFID tag to compatible reader. RFID tags can be passive in nature, deriving their power from the very radio frequencies used by a reader to locate them. RFID tags can be made to look like postage stamp sized stickers, and can be attached to any number of things. Walmart, the US retail giant, has decided to put RFID tags on all of the products it sells. RFID tags are also used for automated payment on highways. In the mobile phone world, RFID tags could be used to load a URL from a poster or advertisement onto the phone's web browser, or to receive contact information from an ID card.
