What is RFID?

Radio Frequency Identification is the use of radio waves to read and capture information stored on a tag attached to an object. A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked.

RFID is useful for tracking items through shops ,or even airports and can be used to facilitate the reading of coded information for example from your credit card or Passport.
