DESCRIPTION

15       ThinkFinger  is a driver for the UPEK/SGS Thomson Microelectronics fin‐
16       gerprint reader (USB ID 0483:2016).  The device is being  found  either
17       as a standalone USB device, built into USB keyboards or built into lap‐
18       tops (mostly Dell, IBM/Lenovo and Toshiba).
19
20       tf-tool is the utility used to acquire and to verify the fingerprints.

OPTIONS

24       --acquire
25              Acquire a fingerprint.  You will be prompted to swipe your  fin‐
26              ger.   It  needs  three  successful swipes to get a fingerprint.
27              This fingerprint is stored in /tmp/test.bir.
28
29       --verify
30              Verify a fingerprint.  tf-tool will  read  a  fingerprint  image
31              from  /tmp/test.bir  and  compare  that with the finger which is
32              being swiped.
33
34       --add-user "login"
35              Acquire a fingerprint for the user identified by login.  If this
36              user  or  the  bir folder /etc/pam_thinkfinger do not exist, tf-
37              tool exits with an error.  If the acquiring process is  success‐
38              ful,   the   fingerprint   is   stored  in  the  bir  folder  as
39              /etc/pam_thinkfinger/login.bir.  This option is  available  only
40              when ThinkFinger has been compiled with PAM support.
41
42       --verify-user "login"
43              Verify  a fingerprint for the user identified by login.  If this
44              user or the bir folder /etc/pam_thinkfinger do  not  exist,  tf-
45              tool  exits  with  an error.  This option is available only when
46              ThinkFinger has been compiled with PAM support.
47
48       --verbose
49              Add more output messages.
