Fundamentals of Radio Frequency Identification

The use of electromagnetic fields to detect and track tags attached to various objects is known as radio frequency identification. It has three components-radio transponder, a radio transmitter and a receiver. Whenever a tag is triggered by an electromagnetic pulse, it transmits digital data back to the receiver. This is the underlying principle on which this domain operates. These devices can be attached to animals, humans, clothes, cash and possessions. These can be applied in diverse are...
