Design and Implementation of Contactless IC Card Unit in the ETC System

This paper introduces the design and implementation of contactless integrated circuit (IC) card in the on-board unit (OBU) module. The MSP430F5418 micro control unit (MCU) for control chip is used in the model,the design of hardware , power management module and software are introduced based on CL RC632 contactless IC card in detail. In addition, hardware interface circuit and Mifare contactless IC card operation flow chart are given.
