IC(Integrated Circuit)卡是在塑料基片上嵌贴上一块特殊的集成电路而制成的,它具有存储容量大、数据保密性好、抗干扰能力强、操作速度快、脱机工作能力强和应用范围广等特点。伴随计算机技术和网络技术的发展,IC卡技术日臻完善,其应用范围也从金融交易和商业消费领域迅速扩展到交通、旅游、电信及医疗等方面。在世界范围内,IC卡目前以每年45％的速度增长。其中仅用于金融交易的IC智能卡的年产量就达到7亿张左右。过去IC卡的应用和消费市场主要集
The IC (Integrated Circuit) card is made by embedding a special integrated circuit on a plastic substrate. The IC has the advantages of large storage capacity, good data confidentiality, strong anti-interference ability, fast operation, strong offline working capability and Wide range of applications and other characteristics. With the development of computer technology and network technology, the technology of IC card has been improved day by day. Its application scope has also rapidly expanded from the areas of financial transactions and commercial consumption to transportation, tourism, telecommunications and medical treatment. IC cards are currently growing at a rate of 45% per year worldwide. The annual output of IC smart cards, which is only used for financial transactions, has reached 700 million. In the past IC card application and consumer market mainly set
