Application of RFID on products tracking and tracing system

Aiming at the requirements of product tracking and tracing in the entire supply chain,a new product tracking model and tracing method based on Radio Frequency IDentification(RFID) semantic event was put forward.Five types of RFID business events were defined,eXtensible Markup Language(XML) element was used to describe the status of product's logistics.By processing concurrent RFID complicated events with buffered priority queuing rules,RFID events could be integrated and matched automatically with the business order of application system.The system architecture,network topology and system security of tracking and tracing system were designed.The traceable RFID information of product could be queried and accessed through Web Service and Short Messaging Service(SMS).The tracking and tracing method based on RFID was applied to the management system of winery which was helpful for anti-counterfeiting and anti-changing product for the franchisers,and stock management.
