The IC card reader is the bridge between the IC card and the application system. It is called the interface device (IFD) in the ISO international standard. The CPU in the IFD is connected to the IC card through an interface circuit and communicates. The IC card interface circuit is a vital part of the IC card reader. According to the actual application system, different IC card reader chips such as parallel communication, half-duplex serial communication and I2C communication can be selected.
