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, tftool 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, tftool 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
