智能卡(SMART CARD)是将带有微处理器的集成电路芯片封装到塑料基片上的一种电子卡片。他具有小巧轻便、存储容量大、数据保密性好、抗干扰能力强、存储可靠、脱机工作能力强和易于使用等特点。随着国家“金卡工程”的实施和开展,它已经广泛应用于银行、交通、邮电、市政、医疗等多种行业。但传统的接触式智能卡由于其采用串行 I/O 的通信方式,存在着传输速度慢、接触磨损、不能防尘等缺点,阻碍了它的继续发展并可能让位干非接触式智能卡。非接触式智能卡(CONTA-CTLESS SMART CARD)是近几年发展起来的新型产品。它在使用时无 A SMART CARD is an electronic card that packages a microprocessor-integrated circuit chip onto a plastic substrate. He has a compact and lightweight, large storage capacity, data confidentiality, anti-interference ability, reliable storage, offline work ability and easy to use and so on. With the implementation and development of the state “Gold Card Project ”, it has been widely used in various industries such as banking, transportation, post and telecommunications, municipal administration and medical treatment. However, the traditional contact smart card has some shortcomings such as slow transmission speed, worn contact and no dust-proof due to its serial I / O communication, which hinders its continuous development and may give way to dry contactless smart card. Contactless smart card (CONTA-CTLESS SMART CARD) is a new product developed in recent years. It is in use without
