RF card reader is one of the key components of a RF card application system. MFRC500 completely integrates all sorts of passive non-contact communication modes and protocols under the frequency of 13.56MHz, which is an advanced integrated RF chip. Based on the study on the related theory and technology of RF card system , this paper presents a RF card read-write system based on MFRC500 chip of the Philips company. The system uses the MCU AT89S52 to control and communications with the MFRC500, combined with the design of the external circuit, achieves to the Read-write operation of the MIFARE card. First introduces the composition and working principle of the system , and then introduces the necessary implement, gives design of the matching circuit and antenna design, as well as the Interface Design of MCU AT89S52 and MFRC500,and the design of the serial communication module, Finally, gives the operation process of the MIFARE card as well as program design. The whole design is completed, and after a self-made circuit board testing, the basic design requirements to meet.
