RFID facilitates processing of product information, making it a promising technology for anti-counterfeiting. A number of RFID anti-counterfeiting mechanisms have recently been proposed. This paper first compares the strengths and weaknesses of these mechanisms, and evaluates possible impacts of threats to RFID. Subsequently, a track-and-trace anti-counterfeiting system using RFID is proposed. The proposed system is aimed at relatively high-end consumer products, and it helps protect genuine products by maintaining the product pedigree and the supply chain integrity. As such, consumers can safeguard their stake by authenticating a product with RFID readers before making payment. The mechanism is relatively simple and easy to implement.
