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.
