Contactless IC Card is one kind of new technology in the field of IC card， which is the bination of Radio Frequency Identification technology and IC card technology. Radio Frequency Identification technology is a new technology of auto identification in recent years. Wireless and bidirectional munication between reader and contactless card is their munication mode to identify the goal and to swap data by radio frequency identification. The power of IC card circuit is supplied by the power of electromagic wave from reader. Because contactless IC card has some advantages over mon IC card such as its high working speed， good anticollision quality and long working distance， there will be a good prospect for it in many fields， such as automatic pricing，identify distinguishing， electric wallet and so on. The contactless IC card reader is one of the key devices of a contactless IC card system. We developed one kind of contactless IC card Acess control system， which is one part of a project and has about 100mm working distance. On the basic of the development of Entrance Guard System， at first this paper generally introduces the contactless IC card， including its feature， type， posing and international standard. Then it introduces the technology of Entrance Guard System. Based on these， the paper discusses the design of the contactless IC card reader in detail， including the circuit design and software design. The reader39。s circuit is made up of buzzer drive circuit， RS232 munication circuit， TX522 card reader module and antenna circuit. The software design includes programming of other circuit and programming of main program. At last the paper introduces the interface design for host puter. According to the study above,designed a access control system based on the contactless IC card.
