SYNOPSIS

9       pcscd [options]
10

OPTIONS

12       -a, --apdu
13              log APDUs and SW using the debug method (see --debug).
14
15       -c, --config dir
16              Specifies  the  directory  dir  as  an  alternate  location  for
17              /etc/reader.conf.d/.  The argument can also be a single configu‐
18              ration file (for backward compatibility).
19
20       -f, --foreground
21              Runs  pcscd  in  the foreground and sends log messages to stderr
22              instead of syslog(3).
23
24       -T, --color
25              force use of colored logs.
26
27       -d, --debug
28              use the lowest log level. Any log message of this level or above
29              will  be  sent  to  stderr  or syslog(3) depending on the use of
30              --foreground.
31
32       --info use info log level. This is the default log level.
33

35              use error log level.
36
37       -C, --critical
38              use critical log level.
39
40       The log levels are ordered as: debug < info < error < critical.  Use  a
41       log level l will log this level and all the levels above it.
42
43       --force-reader-polling
44              ignore the IFD_GENERATE_HOTPLUG reader capability
45
46       -t, --max-thread
47              maximum number of threads (default 200).
48
49              This  is  the  maximum number of clients (SCardEstablishContext)
50              that pcscd can handle.
51
52       -s, --max-card-handle-per-thread
53              maximum number of card handle per thread (default: 200).
54
55              This is the maximum number of  card  handle  (SCardConnect)  per
56              client (SCardEstablishContext).
57
58       -r, --max-card-handle-per-reader
59              maximum number of card handle per reader (default: 200)
60
61              This  is  the  maximum  number of card handle (SCardConnect) per
62              reader.
63
64       -h, --help
65              Displays information about the pcscd command line
66
67       -v, --version
68              Displays the program version number
69
70       -H, --hotplug
71              Ask pcscd to re-read the /etc/reader.conf.d/my_reader.conf files
72              to detect added or removed non-USB readers (serial or PCMCIA).
73
74       -x, --auto-exit
75              pcscd will quit after 60 seconds of inactivity after the release
76              of the last PC/SC context. This is used when pcscd os started on
77              demand by systemd.
78
79       -S, --reader-name-no-serial
80              Do not include the USB serial number in the reader name.

DESCRIPTION

86       pcscd  is  the  daemon  program for pcsc-lite. It is a resource manager
87       that coordinates communications with smart card readers and smart cards
88       and cryptographic tokens that are connected to the system.
89
90       It allows applications to access smart cards and readers using the win‐
91       scard API but without knowing details of the card or reader.
92
93       pcscd coordinates the loading of drivers for card readers.
94

SERIAL SMART CARD READER DRIVERS

96       Smart card reader drivers are placed in the /usr/lib64/pcsc/drivers di‐
97       rectory.  Each  driver is simply an .so file.  pcscd locates the driver
98       using   the   /etc/reader.conf.d/my_reader.conf   files.     See    the
99       reader.conf(5) manual page for more information.
100
101       Some    drivers   are   available   at   https://muscle.apdu.fr/muscle‐
102       card.com/drivers.html.
103

USB SMART CARD READER DRIVERS

105       USB smart card reader drivers are  located  in  /usr/lib64/pcsc/drivers
106       directory   as  a  bundle.  You  shall  NOT  add  a  USB  driver  in  a
107       /etc/reader.conf.d/my_reader.conf file.
108

FILES

110       /etc/reader.conf.d/* : Serial reader configuration files

112       /run/pcscd/pcscd.pid : process id of the running pcscd
113
114       /usr/lib64/pcsc/drivers/ : directory containing bundles for USB drivers
