`--atr`, `-a`

  Print the Answer To Reset (ATR) of the card. Output is in hex byte format

`--card-driver` driver, `-c` driver

`--set-conf-entry` conf, `-S` conf

  Set configuration key, format: section:name:key:value

`--reader` arg, `-r` arg

  Number of the reader to use. By default, the first reader with a present card is used. If arg is an ATR, the reader with a matching card will be chosen.

`--send-apdu` apdu, `-s` apdu

  Sends an arbitrary APDU to the card in the format `AA:BB:CC:DD:EE:FF...`.

`--serial`
