磁卡也称磁印刷品,它是磁记录技术和印刷技术相结合制造出的一种独特的磁记录介质。二次大战后,磁介质得到迅猛发展,磁卡也不例外。美国在19世纪初开始对旅馆、百货商店等发行了住宅卡,这是现代磁卡的起源。到60年代磁卡作为代替现金、小票据的第三流通货币飞跃地发展起来。70年代虽因经济不景气曾一度钝化,但一进入80年代,以电子革命为转机,磁卡再度突入飞跃期,据报道,1989年美国仅信用卡的发行量就达20亿张以上。
Magnetic cards, also called magnetic prints, are a unique type of magnetic recording media created by the combination of magnetic recording technology and printing technology. After World War II, the magnetic medium was rapidly developed, and magnetic cards were no exception. The United States began issuing residential cards to hotels, department stores, etc. in the early 19th century. This is the origin of modern magnetic cards. In the 1960s, magnetic cards developed as a third circulation currency that replaced cash and bills. In the 1970s, although the economy was once passivated due to the economic downturn, as soon as it entered the 1980s, with the electronic revolution as a turning point, the magnetic card again broke into a leap. According to reports, in 1989, the amount of credit cards issued in the United States reached more than 2 billion.
