I want to get ATR of the smartcard. I am using HID omnikey 5321. I am following this link "http://pyscard.sourceforge.net/user-guide.html#requesting-any-card"
so far i have tried:
>>>from smartcard.CardType import AnyCardType
>>>from smartcard.CardRequest import CardRequest
>>>from smartcard.util import toHexString
>>>
>>> cardtype = AnyCardType()
>>> cardrequest = CardRequest( timeout=1, cardType=cardtype )
>>> cardservice = cardrequest.waitforcard()
>>>
>>>>>> cardservice.connection.connect()
i am getting error at the
cardservice.connection.connect()
error like:
raise CardConnectionException('Unable to connect with ptotocol[pcscprotocol] + . '+ScardGetErrorMessage(hresult)
CardConnectionException: Unable to conenct the card with T0 or T1 . Card is not responding to reset.
Because You dont specify the reader to connect:
r=readers()
#r[Number of reader list].
cardservice.connection = r[0].createConnection()
cardservice.connection.connect()
A simple Example:
from __future__ import print_function
from smartcard.Exceptions import NoCardException
from smartcard.System import readers
from smartcard.util import toHexString
for reader in readers():
try:
connection = reader.createConnection()
connection.connect()
print(reader, toHexString(connection.getATR()))
except NoCardException:
print(reader, 'no card inserted')
import sys
if 'win32' == sys.platform:
print('press Enter to continue')
sys.stdin.read(1)
-Another Selecting Reader:
from __future__ import print_function
from smartcard.Exceptions import NoCardException
from smartcard.System import readers
from smartcard.util import toHexString
from smartcard.CardType import AnyCardType
from smartcard.CardRequest import CardRequest
cardtype = AnyCardType()
r=readers()
cardrequest = CardRequest( timeout=10, cardType=cardtype )
cardservice = cardrequest.waitforcard()
print('Available Readers:')
for i in range(len(readers())):
print('[',i+1,']',r[i])
if(len(readers()) < 1):
print("\nNO AVAILABLE READERS!\n")
else:
print("Select you Reader: (Ctrl+C to Exit)")
my_input = input()
selectReader = clamp(int(my_input)-1,0,len(readers()))
print('Selected: ',r[selectReader])
cardservice.connection = r[selectReader].createConnection()
cardservice.connection.connect()
try:
print('Card ATR:',toHexString(cardservice.connection.getATR()),file=f)
except:
print("Cant not Get ATR")
.
