Abstract

Contactless IC Card is one kind of new technology in the field of IC card, which is the combination of RF technology and IC card technology. Because contactless IC card has some advantages over common IC card such as its high working speed,good anti -jamming quality,long working distance, there will be a good prospect for it in many fields such as automatic pricing,identity distinguishing,electric wallet and so on. The contactless IC card reader is one of the key devices of a contactless IC card system. At first this paper generally introduces the IC card,including its feature,type,international standard,key technology and typical usage. After that the MIFARE technology developed by PHILIPS Semiconductors is introduced in detail. Based on these, the paper discusses the design of the contactless IC card reader in detail, including the circuit design and software design. The reader's circuit is made up of power supply circuit,LED and display circuit,buzzer drive circuit,MCU interface circuit ,ZLG500AT read-write module and so on. The software design includes programming of ZLG500AT module and programming of main program.

KEYWORDS: IC Card, contactless, ZLG500A T read-write module, Card reader
