与第一代身份证相比,第二代居民身份证有六大变化:融入IC卡技术、防伪性能提高、办证时间缩短、存储信息增多、有效期重新确定、发放范围扩大。 一是采用非接触式芯片作为“机读”存储器,为IC卡(单页卡式),与我们现在使用的羊城通卡类似。但它比羊城通卡更为先进,芯片储存容量更大,写入的信息可划分安全等级、分区存储。
Compared with the first generation of ID cards, there are six major changes in the second generation of ID cards: IC card technology into the integration of anti-counterfeiting performance, reduce the time permit, storage information increased, the expiration date re-determined to expand the scope of the release. First, the use of non-contact chip as a “machine-readable” memory for the IC card (one-page card), and we now use the Yangcheng Card similar. But it is more advanced than the Yangcheng Tongka, the chip storage capacity is greater, the information written can be divided security level, partition storage.
