Fingerprint Authentication Utility
Fingerprint Logon
The fingerprint utility enables logon to your computer using
fingerprints. During user enrollment, fingerprint samples are
saved and associated with the user’s Windows
®
user
account. When the user attempts to log on again, the user’s
fingerprint is read and compared with the user’s enrolled
fingerprints; if the fingerprint is recognized, user logon is
completed.
The Fast User Switching feature of the Windows
®
operating
system is also supported. If user A is logged on and the
fingerprint utility verifies the fingerprint of user B (who is
already enrolled), the utility recognizes the fingerprint and
switches the users.
If your system supports power-on security, existing
fingerprint samples can be used also for power-on
authentication.
Care and maintenance of your fingerprint reader
Failure to follow these guidelines and/or procedures might
result in damage to the reader or cause reader failure, finger
recognition problems, or lower finger recognition success
rate.
❖ Do not scratch or poke the reader with your nails or any
hard or sharp objects.
❖ Do not press the reader with too much pressure.
❖ Do not touch the reader with a wet finger or any wet
objects. Keep reader surface dry and free of water vapor.
❖ Do not touch the reader with a soiled finger. Minute
foreign particles on a soiled or dirty finger may scratch
the reader.
❖ Do not paste stickers or write on the reader.
❖ Do not touch the reader with a finger or any object with
built-up static electricity.
Observe the following before you swipe your finger on the
reader, whether for fingerprint enrollment/registration or
recognition.
❖ Wash and dry your hands thoroughly.
❖ Remove static electricity from your fingers by touching
any metal surface. Static electricity is a common cause
of reader failures, especially during dry seasons such as
winter.
