RF-related design of the MF RC500 MIFARE reader IC is finished by using MIFARE. A specific antenna and matching circuit are demonstrated to achieve the best performance for a communication with a contactless MIFARE card. These items are discussed in details including the data structure of RF card, its data transmission, relevant time sequence, some parameters for the typical circuits, corresponding matching circuit, EMC, data security, data integrity, the control method for a entrance guard, and so on, and a system about an entrance guard for multimedia classroom, which based on the RF interface theory and the protocol of contactless reader IC, is presented. The system is a good example for modern entrance guard control instead of previously simple performance, inconvenience upgrade, and bad security.
