我有一個OmniKey 5321智能卡讀卡器和一臺裝有Debian的PC。下面的Python代碼讀取卡:在Python中讀取RFID卡中的唯一ID
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]
的Python代碼運行正常,但給我回了很多卡是相同的ATR標籤。給定的ATR是:
3B 8F 80 01 80 4F 0C A0 00 00 03 06 03 00 01 00 00 00 00 6A
我怎麼能讀的東西從卡潮頭?我知道我必須發送一些命令,並且回覆將包含UID,但是如何找到命令?我將如何發送它們?
謝謝!
