Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. The technology requires some extent of cooperation of an RFID reader and an RFID tag.
An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.
Main Article RFID Uses
RFID is becoming increasingly prevalent as the price of the technology decreases. In January 2003 Gillette announced in that it ordered 500 million tags from Alien Technology. Gillette VP Dick Cantwell says the company paid "well under ten cents" for each tag. The Japanese HIBIKI initiative aims to reduce the price to 5 Yen (4 eurocent).
