# Also, the ATR of the inserted card is available (you will likely not need the ATR).

# Also, the maximum number of key containers is readily available:

# Delete the context when finished with the card.
set success [CkScMinidriver_DeleteContext $scmd]

# Sample output:

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