AIM： To research and discuss the practicality of radio frequency identification （RFID） technology. METHODS ： Making use of RFID technology, we chose the reasonable radio frequency（RF） module（ RFM-001 ）, singlechip（ 89C2051 ）, antenna（SA110）, EEPROM（AT24C16） ,and so on, and assembled them in a right way. We gave order to singlechip to control RF module . By using the syntonic frequency emitted by antenna, the valid data traffic could be realized between the RF module and RF card. RESULTS： The roll system was steady and credible. Meanwhile, we completed the topic about the valid identification of RF card and adding and decreasing the amount in RF card. CONCLUSION： Our design is flexible and can be used in many situations; the RFID technology has become more and more important in the social .development.
