RFID Structure is continuously composed of 2 main hardware components.
The transponder which is located on the product to be scanned and the reader which can be either just a reader or a read & write device, depending upon the system design, technology employed and the requirement.
The RFID reader characteristically comprise of a radio frequency module, a controlling unit for configurations, a monitor and an antenna ti investigate the RFID tags.
In addition, a number of RFID readers are in-built with an extra interface allowing them to forward the data received to another system (control system or PC).
