APPLICATION NOTE

RFID Reader using STMicroelectronics µPSD MCU and

CRX14 Coupler to Implement a China National ID Card Reader

The National ID Reader is a demonstration of a reader to read the information from a National ID card and

to display the information on a PC. The demonstration is a reference design for the China National second

generation ID card reader using a µPSD32xx or µPSD33xx 8051 core for the microcontroller, and the

CRX14 as the contactless coupler. The demonstration communicates with the PC using the USB or

RS232 interface. The demonstration complies fully with the ISO14443 type-B standards.

HARDWARE DESCRIPTION OF THE NATIONAL ID READER

The whole system can be divided into two main parts: one is the main control board; the other is the boost-

ed antenna board.
