pcscd - PC/SC Smart Card Daemon
pcscd [
options]
-
-a, --apdu
- log APDUs and SW using the debug method (see
--debug).
-
-c, --config dir
- Specifies the directory dir as an alternate location
for /etc/reader.conf.d/. The argument can also be a single
configuration file (for backward compatibility).
-
-f, --foreground
- Runs pcscd in the foreground and sends log messages to
stderr instead of syslog(3).
-
-T, --color
- force use of colored logs.
-
-d, --debug
- use the lowest log level. Any log message of this level or
above will be sent to stderr or syslog(3) depending on the use of
--foreground.
- --info
- use info log level. This is the default log level.
-
-e, --error
- use error log level.
-
-C, --critical
- use critical log level.
The log levels are ordered as: debug < info < error < critical. Use a
log level l will log this level and all the levels above it.
- --force-reader-polling
- ignore the IFD_GENERATE_HOTPLUG reader capability
-
-t, --max-thread
- maximum number of threads (default 200).
This is the maximum number of clients (SCardEstablishContext) that pcscd can
handle.
-
-s, --max-card-handle-per-thread
- maximum number of card handle per thread (default: 200).
This is the maximum number of card handle (SCardConnect) per client
(SCardEstablishContext).
-
-r, --max-card-handle-per-reader
- maximum number of card handle per reader (default: 200)
This is the maximum number of card handle (SCardConnect) per reader.
-
-h, --help
- Displays information about the pcscd command line
-
-v, --version
- Displays the program version number
-
-H, --hotplug
- Ask pcscd to re-read the
/etc/reader.conf.d/my_reader.conf files to detect added or removed
non-USB readers (serial or PCMCIA).
-
-x, --auto-exit
- pcscd will quit after 60 seconds of inactivity after the
release of the last PC/SC context. This is used when pcscd is started on
demand by systemd.
-
-S, --reader-name-no-serial
- Do not include the USB serial number in the reader
name.
-
-I, --reader-name-no-interface
- Do not include the USB interface name in the reader
name.
pcscd is the daemon program for pcsc-lite. It is a resource manager that
coordinates communications with smart card readers and smart cards and
cryptographic tokens that are connected to the system.
It allows applications to access smart cards and readers using the WinSCard API
but without knowing details of the card or reader.
pcscd coordinates the loading of drivers for card readers.
Smart card reader drivers are placed in the
/usr/lib/pcsc/drivers
directory. Each driver is simply an
.so file. pcscd locates the driver
using the
/etc/reader.conf.d/my_reader.conf files. See the
reader.conf(5) manual page for more information.
Some drivers are available at
https://muscle.apdu.fr/musclecard.com/drivers.html.
USB smart card reader drivers are located in
/usr/lib/pcsc/drivers
directory as a bundle. You shall NOT add a USB driver in a
/etc/reader.conf.d/my_reader.conf file.
