JMY612 series are RFID reader/writer module with RS232C serial ports. JMY612 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 through RS232C interface. And the module and antenna are separate design. The impedance between RF module and antenna was tuned by impedance analyzer. And then the module has excellent performance and stability. The module and antenna is linked by 50ohm coaxial line. The performance is good, though the wire can reach 10m. Normally the wire should be 60cm that is the module's best performance and stability.
