SLE4442卡无反应

Question

我有个项目需要用内存卡玩。我需要读写卡。

我的 reader 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)

我用的卡是：SLE4442内存卡（丢了link）

我在 ubuntu 上使用 pcsc-lite 和 pcsc-tools

当我使用'pcsc_scan'命令时，它可以成功读取reader模型，但卡没有反应。像这样的事情：

leo@leo-ThinkPad-S3-S431:~$ pcsc_scan

Reader 0: Alcor Micro AU9540 00 00
Card state: Card inserted, Unresponsive card,

但是如果我用的是自己在用的银行卡（我知道不是内存卡），但是这样的话，它得到了一个ATR响应：

  Card state: Card inserted, 
  ATR: 3B 68 00 00 00 73 C8 40 13 00 90 00

ATR: 3B 68 00 00 00 73 C8 40 13 00 90 00
+ TS = 3B --> Direct Convention
+ T0 = 68, Y(1): 0110, K: 8 (historical bytes)
  TB(1) = 00 --> VPP is not electrically connected
  TC(1) = 00 --> Extra guard time: 0
+ Historical bytes: 00 73 C8 40 13 00 90 00
  Category indicator byte: 00 (compact TLV data object)
    Tag: 7, len: 3 (card capabilities)
      Selection methods: C8

        - Logical channel number assignment: by the card
        - Maximum number of logical channels: 4
    Mandatory status indicator (3 last bytes)
      LCS (life card cycle): 00 (No information given)
      SW: 9000 (Normal processing.)

Possibly identified card (using /usr/share/pcsc/smartcard_list.txt):

MASTERCARD issued by MLP (Marschollek, Lautenschl?ger and Partner)
G&D 12696-GDM-10/11 DEBIT CARD issued by BANCO DE CREDITO DEL PERU

对比了一下，好像问题出在卡上。

我也猜是不是因为我买的卡不符合reader？在 eBay 上，卡片的详细信息如下： [卡片销售页面][1]

[1]: http://i.stack.imgur.com/O6v1o.png 提供部分卡reader卡支持的型号（部分卡支持所有reader）。也许我的卡不支持我的 reader?

或者我可能需要先在卡上做任何事情然后我才能得到 ATR 响应？

一张卡无法与 reader 兼容，反之亦然。注意SLE4442是一张memory卡，这意味着通信是同步的，使用两线协议而不是异步T=0或T=1。

根据Alcor Micro，reader芯片支持双线，所以你的卡可能有问题。
