我有一个 OmniKey 5321 智能卡读卡器和一台装有 Debian 的 PC。以下 Python 代码读取卡片：

from smartcard.CardMonitoring import CardMonitor, CardObserver
from smartcard.util import *
import sys

class printobserver( CardObserver ):
    def update( self, observable, (addedcards, removedcards) ):
        for card in addedcards:
            print "+Inserted: ", toHexString( card.atr )
        for card in removedcards:
            print "-Removed:  ", toHexString( card.atr )

try:
    print "Insert or remove a smartcard in the system."
    print ""
    cardmonitor = CardMonitor()
    cardobserver = printobserver()
    cardmonitor.addObserver( cardobserver )
    raw_input('Press Enter to exit\n')
except:
    print "Unexpected error: ", sys.exc_info()[0]

Python 代码运行良好，但为许多卡片返回了相同的atr标签。给定的 atr 是：

3B 8F 80 01 80 4F 0C A0 00 00 03 06 03 00 01 00 00 00 00 6A

我怎样才能从卡片中读取一些独特的东西？我知道我必须发送一些命令，回复将包含 UID，但我怎样才能找到命令？我将如何发送它们？

谢谢！

连接到卡（或实际上是读卡器）后，您可以发送 PC/SC 标准化命令以从读卡器获取卡 UID：

FF CA 00 00 00
