Radio Frequency Identification (RFID) is a technology designed to allow objects, animals and even human beings to be identified, located, and tracked using radio frequency signals. The history of RFID can be traced back to World War II, when it was used by the British to identify friendly aircraft. The technology has developed over the years and is now used in a wide range of...
