JMY628 is a RFID read/write module with UART, IIC or USB port. JMY628 has various functions and supports multi ISO/IEC standard of contactless card. The RF protocol is complex, but the designer combined some frequent used command of RF card and then user could operate the cards with full function by sending simple command to the module. The modules build in SAM slot. It could operate contact smart card according to ISO7816. The module and antenna is integrated. The impedance between RF circuit and antenna was tuned by impedance analyzer, and then the module has excellent performance and stability. There is ferrite plate between main PCB and antenna, so such design applies to some metallic-around systems.
