information via radio waves and can be used to track the number
and location of the objects into which tags have been inserted.
Wal-Mart deployed radio frequency identification (RFID)
technology on Jan. 1, 2005.
A RFID system consists of three main components: a tag, a reader,
and a computer system.
Typically, RFID tags are made by joining a radio antenna with a
microchip and then surrounding the two with a protective case.
These tags can then be attached individually to the physical
product itself or to the product packaging.
While the useful information is stored inside of the tag, it needs a
reader to detect, collect, and decode the information.
Finally, a computer system is used to interpret, filter, and store the
collected data in a meaningful way.
