Executive Summary

Radio Frequency IDentification (RFID) is a promising new technology widely deployed for supply-chain and inventory management, retail operations and more generally, automatic identification. The advantage of RFID over barcode technology is that it does not require line-of-sight reading. Furthermore RFID readers can interrogate RFID tags (devices) at greater distances, faster and concurrently. One of the most important advantages of RFID technology is that tags have read/write capability, allowing stored information to be altered dynamically.
