NAME

       tf-tool - Utility to acquire and to verify fingerprints

SYNOPSIS

       tf-tool [OPTION]

DESCRIPTION

       ThinkFinger  is  a  driver  for  the  UPEK/SGS Thomson Microelectronics
       fingerprint reader (USB ID  0483:2016).   The  device  is  being  found
       either  as  a  standalone USB device, built into USB keyboards or built
       into laptops (mostly Dell, IBM/Lenovo and Toshiba).

       tf-tool is the utility used to acquire and to verify the  fingerprints.

OPTIONS

       --acquire
              Acquire  a  fingerprint.   You  will  be  prompted to swipe your
              finger.  It needs three successful swipes to get a  fingerprint.
              This fingerprint is stored in /tmp/test.bir.

       --verify
              Verify  a  fingerprint.   tf-tool  will read a fingerprint image
              from /tmp/test.bir and compare that with  the  finger  which  is
              being swiped.

       --add-user "login"
              Acquire a fingerprint for the user identified by login.  If this
              user or the bir folder /etc/pam_thinkfinger do  not  exist,  tf-
              tool   exits  with  an  error.   If  the  acquiring  process  is
              successful, the fingerprint is  stored  in  the  bir  folder  as
              /etc/pam_thinkfinger/login.bir.   This  option is available only
              when ThinkFinger has been compiled with PAM support.

       --verify-user "login"
              Verify a fingerprint for the user identified by login.  If  this
              user  or  the  bir folder /etc/pam_thinkfinger do not exist, tf-
              tool exits with an error.  This option is  available  only  when
              ThinkFinger has been compiled with PAM support.

       --verbose
              Add more output messages.

FILES

       /etc/pam_thinkfinger
              The  default  folder  where  the fingerprint for login users are
              stored
       /tmp/tmp.bir
              The file used when acquiring or verifying a fingerprint
