In this paper, the authors are to manage the student's attendance by using RF ID cards and updating it to the student or parent through SMS by using GSM module. An Attendance Management System (AMS) based on TCP/IP protocol is designed and realized. This paper expounds the principle of the RFID reader device in AMS, its hardware and software design. The reader device takes ARM LM3S9B90 as the core and Philips's MFRC531 as the transceiver chip of RFID reader. In application, the system works stable and has good real-time performance.
