Short for radio frequency identification, RFID technology is an IT system that transmits signals without the presence of
physical gadgets, but wirelessly. It is categorized under automatic identification technologies that have well established protocols [2]. The working of an RFID system is very simple (Fig.2). The system utilizes tags that are attached to various components to be tracked. The tags store data and information concerning the details of the product of things to be traced. The reader read the radio frequency and identifies tags .The antenna provides the means for the integrated circuit to transmit its information to the reader.
