pcscd - PC/SC Smart Card Daemon

SYNOPSIS
pcscd [options]

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 /usr/local/etc/reader.conf.d/reader.conf.

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

-T, --color

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 rescan the USB buses for added or removed readers and re-read the /usr/local/etc/reader.conf.d/reader.conf file to detect added or removed non-USB readers (serial or PCMCIA).

-x, --auto-exit
    pcscd will quit after 60 seconds of inactivity. This is used when pcscd os started on demand by systemd.

DESCRIPTION
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.

SERIAL SMART CARD READER DRIVERS
Smart card reader drivers are placed in the /usr/local/lib/pcsc/drivers/ directory. Each driver is simply an .so file. pcscd locates the driver using the /usr/local/etc/reader.conf.d/reader.conf file. See the reader.conf(5) manual page for more information.

Some drivers are available at http://pcsclite.alioth.debian.org/musclecard.com/drivers.html.

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

FILES
/usr/local/etc/reader.conf.d/reader.conf : Reader configuration file

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

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