将肉眼可见的各种符号印记在看得见摸得着的纸张上,是人类沿用了数千年的信息记录方式,现代电磁技术的发展却可以将信息存储在磁或硅介质上,这极大地方便了人们的生活;而微处理器技术的不断进步使得计算机一小再小,直至现在可以将它“装”入口袋中。现代社会中已经走进千家万户的IC卡,便是处理和存储技术在缩微化方向不断取得进步的结晶。而IC卡技术又在不断地精益求精……
The various visible signs of the visible paper on the visible and tangible, human use of thousands of years of information follows the recording method, the development of modern electromagnetic technology but can store information on the magnetic or silicon media, this extremely The earth has brought convenience to people’s lives; and advances in microprocessor technology have made computers “small” into the pocket now. In modern society, IC cards that have entered every household are the crystallization of processing and storage technologies that continue to make progress in the miniaturization. The IC card technology is constantly improving ...
