# If we are successful, the name of the currently inserted smart card is available:
$cardName = $scmd->cardName();
print "Card name: " . $cardName . "\r\n";

# Also, the ATR of the inserted card is available (you will likely not need the ATR).
print "ATR: " . $scmd->atr() . "\r\n";

# Also, the maximum number of key containers is readily available:
print "Max number of key containers = " . $scmd->get_MaxContainers() . "\r\n";

# Delete the context when finished with the card.
$success = $scmd->DeleteContext();
if ($success == 0) {
    print $scmd->lastErrorText() . "\r\n";

# Sample output:

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