The Research and Design of Card Reader Based on RFID
This paper designed a RFID-based card reader system, which is based on Cortex-M3 LM3S9B90 chip controller, using MRC531 as the base station chip and Mifare1S50 as card read-write. The system realizes the identification and data reading and writing of Mifare1S50 card with a frequency of 13.56MHz, while it can also communicate with the host computer conveniently. The communications use open-source TCP / IP protocol stack LWIP.
