sell 13.56MHz rfid module JMY620C Interface: I2C, UART
JMY620 series are 13.56MHz RFID reader/writer module with UART and IIC serial ports. 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. JMY620 adopts surface mount installation form. Small size is a major feature of JMY620. JMY620 has many kinds of funtions and it can support various contactless IC card under international standards. 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 JMY620 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.
