随着科学技术的发展和人民生活水平的提高,各种信用卡正以飞快的速度进入社会生活的各个领域,由于大规模集成电路的发展而诞生的集咸电路信用卡的应用将尤为广泛。集成电路卡又称IC卡按性能可分为:存储卡(无CPU),智能卡(带有CPU),超级智能卡(卡片式微机)。IC卡中应用的存储器主要有RAM,ROM,PROM,EPROM,EEPROM,目前存储十多以EEPROM为主要存贮器件,IC卡上的印制电路板上有8个电接触点,其中6个 With the development of science and technology and the improvement of people’s living standards, various credit cards are entering various fields of social life at a rapid pace. The application of credit card set due to the development of large-scale integrated circuits will be especially extensive. IC card, also known as IC card by performance can be divided into: memory card (without CPU), smart card (with CPU), super smart card (card microcomputer). The memory used in IC cards mainly includes RAM, ROM, PROM, EPROM and EEPROM. At present, more than 10 EEPROMs are stored as the main storage devices. There are 8 electrical contacts on the printed circuit board of the IC card, of which 6
