Aiming at the problems such as low efficiency of traditional attendance machines, and body absorption, metal interference, limited number of identification existed in practical application of passive RFID, a wireless attendance method of home-school interaction based on active 2.4 GHz RFID technology is proposed. Compared with the traditional attendance method, it is more accurate, convenient and efficient by waking up and positioning 2.4 GHz RFID tags by u sing 125 kHz triggers. What is more, it has extended the service life of active RFID effectively. Further more, the test scenario was constructed by lower frequency trigger, card readers, RFID tags and other equipments, in which wireless attendance system for home-school interaction was tested for 20 days. The test results show that the wireless attendance system for home school interaction system based on RFID technology has high reliability and practicality.
