pcscd PC/SC Smart Card Daemon

pcscd [options]

a, apdu
log APDUs and SW using the debug method (see debug).

c, config file
Specifies the file file as an alternate location for /etc/reader.conf.

f, foreground
Runs pcscd in the foreground and sends log messages to stderr instead of syslog(3).

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.

use error log level.

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.

h, help
Displays information about the pcscd command line

v, version
Displays the program version number

H, hotplug
Ask pcscd to rescan the USB buses for added or removed readers and re read the /etc/reader.conf file to detect added or removed non USB readers
(serial or PCMCIA).

pcscd is the daemon program for pcsc lite and the MuscleCard framework. It is a resource manager that coordinates communications with smart card readers and
smart cards and cryptographic tokens that are connected to the system.

pcscd is normally started at boot time from /etc/init.d/pcscd. It allows applications to access smart cards and readers without knowing details of the card
or reader.

pcscd coordinates the loading of drivers for card readers.

The purpose of pcsc lite is to provide a cross compatible API (called winscard) for migrating Windows based PC/SC applications to Unix.

At startup, pcscd loads the smart card reader drivers specified in the /etc/reader.conf file (or specified using config file).

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 file. See the reader.conf(5) manual page for more information. Drivers are available at

USB smart card reader drivers are located in /usr/lib/pcsc/drivers directory as a bundle. You shall not add a USB driver in /etc/reader.conf file.

/etc/reader.conf : Reader configuration file

/etc/init.d/pcscd : pcscd startup script

/var/run/pcscd/ : process id of the running pcscd

/usr/lib/pcsc/drivers : directory containing bundles for USB drivers
