Package smartcard :: Class Session

Class Session

The Session object enables programmers to transmit APDU to smartcards.

This is an example of use of the Session object:

import smartcard reader=smartcard.listReaders() s = smartcard.Session(reader[0]) SELECT = [0xA0, 0xA4, 0x00, 0x00, 0x02] DF_TELECOM = [0x7F, 0x10] data, sw1, sw2 = s.sendCommandAPDU(SELECT+DF_TELECOM) print data, sw1, sw2 s.close() print `s`

init(self, readerName=None, cardServiceClass=None)
(Constructor)

source code

Session constructor. Initializes a smart card session and
connect to the card.

readerName:         reader to connect to; default is first PCSC reader
cardServiceClass:   card service to bind the session to; default
                    is None

close(self)

source code

Close the smartcard session.

Closing a session will disconnect from the card.

sendCommandAPDU(self, command)

source code

Send an APDU command to the connected smartcard.

command:    list of APDU bytes, e.g. [0xA0, 0xA4, 0x00, 0x00, 0x02]

returns a tuple (response, sw1, sw2) where
        response is the APDU response
        sw1, sw2 are the two status words
