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.

JMY622 series are 13.56MHz RFID reader/writer module with UART and IIC serial ports. The module would meet EMV2000, EMV2010 and PBOC 2.0 standards. And the module and antenna is linked by 50ohm coaxial line. The impedance between RF module and antenna was tuned by impedance analyzer; so the module has excellent read/write performance and stability. Though the wire can reach 10m, but the performance is good. Normally the wire should be 60cm that is the module's best performance and stability. JMY622 adopts surface mount installation form. Small size is a major feature of JMY622. JMY622 has many kinds of funtions and it can support various contactless IC card under international standars. Meanwhile it can support the cards from different suppliers. Designer classified&integrated the operation commands for contactless IC cards. In this situation, the uesr can operate it easily via sending simple commands. The most important features for JMY622 is that it can support contactless IC cards(T=CL) fully. It can send and receive more than 256 Bytes APDU commands and also support FSDI=8.
