__init__(self, reader)
(Constructor)

source code 

Construct a new PCSC card connection.

reader: the reader in which the smartcard to connect to is located.

Parameters:
  • reader - name of the reader in which the smartcard to connect to is located.
Overrides: object.__init__

__del__(self)
(Destructor)

source code 

Destructor. Clean PCSC connection resources.

Overrides: CardConnection.CardConnection.__del__

connect(self, protocol=None, mode=None, disposition=None)

source code 

Connect to the card.

If protocol is not specified, connect with the default connection protocol.

If mode is not specified, connect with SCARD_SHARE_SHARED.

Transmit an apdu to the card and return response apdu.

Parameters:
  • bytes - command apdu to transmit (list of bytes)
  • protocol - the transmission protocol, from CardConnection.T0_protocol, CardConnection.T1_protocol, or CardConnection.RAW_protocol
Returns:
a tuple (response, sw1, sw2) where sw1 is status word 1, e.g. 0x90 sw2 is status word 2, e.g. 0x1A response are the response bytes excluding status words
Overrides: CardConnection.CardConnection.doTransmit

doControl(self, controlCode, bytes=[])

source code
