我有一个需要玩存储卡的项目。我需要阅读并写入卡片。
我的阅读器型号是:Alcor Micro AU9540(http://www.ebay.com/itm/NEW-HIGH-SPEED-USB-EMV-PS-SC-SMART-CARD-CHIP-READER-AND-WRITER-SUPPORT-ISO-7816-/172165900399?hash=item2815e3286f:g:zJoAAOSwDuJWxOcc)
我使用的卡是:SLE4442存储卡(我丢失了链接)
我在ubuntu上使用pcsc-lite和pcsc-tools
执行此操作当我使用'pcsc_scan'命令时,它可以成功读取读卡器型号,但卡片无响应。这样的事情:

但如果我使用我自己的使用中的银行卡(我知道它不是存储卡),但是这样的话,它得到了ATR响应:

通过比较,似乎卡上出现了问题。
我也猜测是不是因为我买的卡与读卡不匹配?在eBay上,卡的详细信息如下: [卡片销售页面] [1]
[1]:http://i.stack.imgur.com/O6v1o.png它提供了卡支持的一些型号的读卡器(一些卡支持所有读卡器)。也许我的卡不支持我的读卡器?
或许我需要先在卡片上做任何事情,然后才能得到ATR回复?
答案 0 :(得分:0)
一张卡片与读卡器不兼容可以做很多事情,反之亦然。请注意,SLE4442是内存卡,这意味着通信是同步的,并使用双线协议而不是异步T = 0或T = 1。
根据Alcor Micro,读卡器芯片支持双线,因此您的卡可能有缺陷。
