JMY6021 is a series of RFID read/write module with IIC, UART, RS232C and USB communication port. It 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. The impedance between RF circuit and antenna was tuned by impedance analyzer, so the module has excellent performance and stability. It has EMV2010 certification ability in RF part, and with 2 SAM slots. Also very popular full fill payment system usage.
