To solve the problem of low efficiecy in the traditional artificial packaging for fresh products, a fresh products packaging system was designed based on RFID. Combining the RFID technology, the users’ interactive software and the database technology, the proposed system utilized the rapid writing and reading performance of RFID to improve packaging operation and sorting operation by writing and reading fresh products’ message, respectively. Therefore the system can enhance the intelligentize of the E-commerce enterprise. The test system verified by the instance can finish packaging and sorting operation for fifty boxes. Therefore the system can identify accurately RFID tag, and can effectively improve the packaging processing.
