JMY6073 is a RFID read/write module with UART, IIC ports. JMY6073 has various functions and supports multi ISO/IEC standard of contactless card. The RF protocol is complex. 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 has a length of 506 bytes command buffer could send APDU over 256 bytes to T=CL smart cards. The modules support FSDI=8 of ISO14443-4. 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.
