摘　　要： 双界面卡是目前技术上最先进的IC卡，它是既有接触界面又有非接触界面的IC卡。因为接触式IC卡存在容易磨损、受使用环境限制、交易速度慢等缺点，很大程度上制约了接触式IC卡的应用领域。非接触式IC卡虽然弥补了接触式IC卡的不足，但其自身的存储容量、安全性等问题也存在缺陷，不能满足特定要求。因此在一卡多用系统中，有的应用使用接触式IC卡，有的应用使用非接触式IC卡，基于这些需求，出现了双界面卡。在双界面卡广泛使用的今天，市面上出现了更多的便民服务，如菜市场、早餐点、公交车、地铁、停车收费场、影院、小商户等都开始使用小额支付业务。银行方面也更多的开展了与小额支付相关的业务拓展。因此研发双界面小额支付模块变得十分必要。 本课题研究目标是开发一款双界面小额支付模块，它可以通过读取不同类型的卡片完成小额刷卡支付功能。双界面支付模块具备读写接触式IC卡、非接触式IC卡的能力，并完成交易数据的处理，可通过串口将数据上传至PC或其他管理终端。作者在实践中重点完成了接触式IC卡支付模块、RFID小额支付模块的设计与研发工作。 本文介绍了IC卡的相关知识，其次对系统进行了总体介绍，包括需求分析、系统简介、设计难点。接下来重点介绍了双界面小额支付模块的硬件设计和软件设计。其中硬件设计主要包括系统的硬件组成、各主要功能模块的芯片选取、以及核心的各模块设计电路。软件设计重点介绍了接触式IC卡模块、RFID小额支付模块的驱动设计。最后简单介绍了双界面小额支付模块的测试，并对整篇论文进行了总结，指出了系统设计的优点和不足。 Dual-interface card is currently the most technically advanced IC card which has a touchinterface and non-contact interface. Though contact-type IC card is easy to wear, subject toenvironmental restrictions, slow trading and other disadvantages, these shortcomings restrictthe application of contact-type IC card to a large extent. Non-contact IC card makes up for thelack of contact-type IC card, but its storage capacity, security, and other issues are also flawedand can not meet certain requirements. Consequently, in the multi-application card operationsystem, some applications are for contact-type IC cards, while some applications are forcontactless IC card. Based on these needs, dual-interface cards come out. Dual-interface cardsare widely used today, which have appeared on the market with more convenient services, forexample, markets, early meals, bus, subway, parking, cinema, small businesses are beginningto use petty sum payment business. Banks are also more associated with petty sum paymentbusiness. Research on dual-interface for petty sum payment module becomes necessary. The research goal is to develop a module with dual-interface for micro-payment; it canread different types of cards to complete petty sum payment functions. This module has theability of reading and writing contact-type IC card and contactless IC card，completing thetransaction data via the serial port terminal to upload data to PC or other management. Inpractice, the author focuses on the design and development of contact-type IC card paymentmodule and RFID micro-payment module. This paper introduces the knowledge of IC card followed by a system overview,including requirements analysis, system overview, and difficulties in design. Then it focuseson the hardware design and software design of dual-interface micro-payment module.Hardware design includes hardware system, the chip selection of major functional modulesand circuit design of the core module. Design of software highlights driven design of thecontact-type IC card module and RFID micro-payment module. Finally it introduces the testabout dual-interface micro-payment module, sums up the whole thesis, and points out thestrengths and weaknesses of system design.
