JMY6801 is a series of RFID read/write module with RS232C communication port. JMY6801 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 module and antenna is integrated and ferrite plate under the antenna, good performance for metallic-around environments to supply more convenience to design structure of the system. The impedance between RF circuit and antenna was tuned by impedance analyzer, and then the module has excellent performance and stability.
