I need to know if there any kind of unique object that i can use to differentiate between smart cards for example if i have 1000 smart cards and i need to differentiate between them without pre-write any values on them

is there any default unique value which is a factory default built-in value like the mac address for the network cards

????

how can i retrieve this value if it was there??

这取决于智能卡的类型。

您将无法使用 ATR,因为这对于每张卡都是相同的。但是,一些智能卡支持“CHUID”(持卡人唯一 ID),许多 MIFARE 卡都支持这一点。但是,有时 MIFARE 卡被配置为报告卡 ID 的伪随机值,以消除有人跟踪卡的机会。

我的公司为智能卡创建了一个基于 Web 浏览器的脚本环境,可以帮助您入门,paypass 演示展示了如何获取 paypass 卡的卡 ID:
