smartcard.Session

class documentation

class Session:

Constructor: Session(readerName, cardServiceClass)

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`)

Method	`__init__`	Session constructor. Initializes a smart card session and connect to the card.
Method	`__repr__`	Returns a string representation of the session.
Method	`close`	Close the smartcard session.
Method	`getATR`	Returns the ATR of the connected card.
Method	`sendCommandAPDU`	Send an APDU command to the connected smartcard.

Instance Variable	`readerName`	Undocumented

def __init__(self, readerName=None, cardServiceClass=None): ¶

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

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

def __repr__(self): ¶

Returns a string representation of the session.

def close(self): ¶

Close the smartcard session.

Closing a session will disconnect from the card.

def getATR(self): ¶

Returns the ATR of the connected card.

def sendCommandAPDU(self, command): ¶

Send an APDU command to the connected smartcard.

Parameters
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
