This is Mr. Harry Yang from Jinmuyu Electronics Co., Ltd. if you want to know of the details about the following 13.56MHz rfid reader or rfid module, please contact me.

JMY628 is a series of RFID read/write module with UART or IIC communication 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 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.
