Introduction JMY620 by the user via an IIC or UART interface to send commands to complete a modular circuit for non-contact IC card reading and writing operations. The module conforms EMV2000, EMV2010 and PBOC 2.0 standard. JMY620 series of non-contact IC card reader module using 50ohm coaxial cable between the antenna, RF circuits and antennas using an impedance analyzer adjusted to match the impedance to achieve a very good read and write performance and very good stability, connection length You can still reach 10 meters to ensure good read results, the design of the user of this connection distance is generally 60cm, can achieve the best performance and stability. JMY620 installation form uses surface mount, ultra-small size is a major feature of JMY620. JMY620 many functions, supports a variety of non-contact IC card international standards, to support a number of different suppliers cards. Designers of the non-contact IC card orders are classified integration, so users IIC or UART command module issue is relatively simple, but was able to complete the full operation of the various non-contact IC card.
