Radio Frequency Identification (RFID) Technology is receiving considerable attention as an enabling technology that can improve supply chain asset tracking and inventory control. RFID is an automatic identification technology whereby digital data encoded in a transponder is captured by a reader using radio waves. The communication process between the transponder and the reader involves the transmitting of energy by the reader's antenna, which is picked up by transponder's antenna and some of it reflected back using backscattering modulation. Nonetheless RFID is still a relatively immature technology and many of its characteristics in real-life industrial scenarios are not yet fully understood. For example, the performance of RFID can be severely hampered by the presence of metals and liquids in the tagged product or extreme conditions in the environment. Hence it is important to examine the practical feasibility of RFID in harsher surroundings. This research is an attempt to examine the practical issues associated with using RFID in a complex metal environment and the interference of RF waves caused by metals in particular. The work also highlights various methods which when applied can improve the performance of RFID significantly
