ScMinidriver - Acquire Context with Smart Card or USB Token

See more ScMinidriver Examples

Initializes communication with the card inserted in the given reader (or a USB token). Reader names can be discovered via the SCard.ListReaders or SCard.FindSmartcards methods. If successful, the Atr and CardName properties will be set. CkPython

success = False

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

scmd = chilkat.CkScMinidriver()

# Reader names (smart card readers or USB tokens) can be discovered
# via List Readers or Find Smart Cards
readerName = "Alcor Micro USB Smart Card Reader 0"
success = scmd.AcquireContext(readerName)
if (success == False):
    print(scmd.lastErrorText())
    sys.exit()

# If we are successful, the name of the currently inserted smart card is available:
cardName = scmd.cardName()
print("Card name: " + cardName)

# Also, the ATR of the inserted card is available (you will likely not need the ATR).
print("ATR: " + scmd.atr())

# Also, the maximum number of key containers is readily available:
print("Max number of key containers = " + str(scmd.get_MaxContainers()))

# Delete the context when finished with the card.
success = scmd.DeleteContext()
if (success == False):
    print(scmd.lastErrorText())

# Sample output:

# Card name: IDPrime MD T=0
# ATR: 3B7F96000080318065B0855956FB120FFE829000
# Max number of key containers = 20
