Abstract: | Traditional method in the checking attendance, not only takes the massive teaching time, also cannot really and accurately reflect the students' attendance . According to practical application's demand, we design RFID the microreade based on the radio frequency chip-U2270B and Freescale MCU which is used to check the students' attendance. The paper expounds detailedly how to choose the dual-frequency between 125KHz and 134KHz, how to keep low power consumption of the Attendance System,and how to store records from the software and the hardware designation. |
