JMY622 connects outside antenna by 50ohm coaxial cable. It fully supports ISO14443 and ISO15693 cards. It has EMV2010 certification ability, also could be set RF output level. The surface mount and very small module size design are fit to portable devices. 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 split. The impedance between RF circuit and antenna was tuned by impedance analyzer, and then the module has excellent performance and stability.
