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

stored
