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).

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

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.
