The implementation of Radio Frequency Identification (RFID) technology in industrial manufacturing and retail supply chain management has seen strong growth in recent years. This is partly due to Wal-Marts RFID mandate to its suppliers. As more companies along the global supply chain adopt RFID, RFID tags embedded can be expected to proliferate in virtually every industrial product, ranging from computers to automobiles, in the near future. Large retailers likeWal-Mart and government agencies such as the U.S. Department of Defense (DoD) have driven recent developments in RFID technology. This in turn has a diffusion effect on hundreds of suppliers and manufacturers as their products are required to be tagged before shipping to these giant customers.
RFID technology provides a good alternative to automatically reading and writing product information. In addition to recording the identity of an object, RFID technology also documents its current status, recent past, and immediate future.
