OPERATION OF RFID

     A Radio Frequency Identification (RFID) system uses wireless radio communication technology to uniquely identify tagged objects or people. There are three basic components to an RFID system:

The Basic Building Blocks of an RFID System

i. A Tag (sometimes called a transponder)
   It composed of a semiconductor chip, an antenna and sometimes a battery.

ii. An Interrogator (sometimes called a reader or a read / write device)

-                    It composed of antenna, an RF electronics module and control electronic module.

iii. A controller (sometimes called a host)

-                  Most often takes the form of a PC or a workstation running database and control (often called middleware) software.
