JMY602 series are RFID reader/writer module with IIC or UART or USB ports. There are 2 SAM card slots in the module which supports SAM cards compliant with ISO7816 (T=0 and T=1). And also it supports SAM card(38400bps)which was used in domestic card management system.
JMY602 has various functions and supports multi ISO/IEC standard of contactless card; the cards from different suppliers. 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 are integrated design. The impedance between RF module and antenna was tuned by impedance analyzer. And then the module has excellent performance and stability.
