RFID

Radio Frequency Identification System uses radio wave / electromagnetic wave as a medium.

RFID is a highly reliable way to electronically control, detect and track a variety of items using FM transmission methods. A small tag, or transponder, affixed to or embedded into virtually any object individually identifies the object using a unique, factory-programmed, unalterable code.
 
Components of RFID Systems
A RFID system has three components:
  • RFID tags that are electronically programmed with unique information.
  • Antennae or sensors to read the tags.
  • A Reader (read/write Unit) to communicate with the tags.
Tags/ Transponder
The transponder, which represents the actual data-carrying device of an RFID system, normally consists of a coupling element and an electronic microchip. The mode of communication between the reader and the tag is wireless means air interface between the two.
Antennae

These are radio frequency devices designed to detect and read intelligent tags to obtain the information stored on them. The antenna generates a field of power to read the tag(s) within range. Each tag generates its own signal to provide its unique data to the antenna.

 RFID Antenna
Reader (Read/write unit)

The read/write unit sends out a signal causing the transponder to respond and transfer its own signal, containing an encoded information. The transponder signal is decoded in the read/write unit and sent to a selected control unit (e.g. host computer).
