opensc-tool - generic smart card utility

opensc-tool [OPTIONS]

The opensc-tool utility can be used from the command line to perform miscellaneous smart card operations such as getting the card ATR or sending arbitrary APDU commands to a card.


Print the OpenSC package release version.

--atr, -a

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

--card-driver driver, -c driver

Use the given card driver. The default is to auto-detect the correct card driver. The literal value ? lists all available card drivers.


Lists algorithms supported by card

--info, -i

Print information about OpenSC, such as version and enabled components.

--list-drivers, -D

List all installed card drivers.

--list-files, -f

Recursively list all files stored on card.

--list-readers, -l

List all configured readers.

--name, -n

Print the name of the inserted card (driver).

--get-conf-entry conf, -G conf

Get configuration key, format: section:name:key

--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.

--reset [type],

Resets the card in reader. The default reset type is cold, but warm reset is also possible.

--send-apdu apdu, -s apdu

Sends an arbitrary APDU to the card in the format AA:BB:CC:DD:EE:FF.... Use this option multiple times to send more than one APDU.

The built-in card drivers may send additional APDUs for detection and initialization. To avoid this behavior, you may additionally specify --card-driver default.


Print the card serial number (normally the ICCSN). Output is in hex byte format

--verbose, -v

Causes opensc-tool to be more verbose. Specify this flag several times to enable debug output in the opensc library.

--wait, -w

Wait for a card to be inserted.
