Contactless Smart Card Reader Module
‐ Uart, SPI, and I2C Interface ‐
Model : MIC‐001
Thank you for purchasing our products.
The contactless smart card reader module
is mainly to support the reader and peer2peer function. The
small footprint size of the module and facility interface make it easily to integrate into all the platform. The
module communicates with a host computer or terminal using a standard Uart, SPI, I2C interface.
