119 Utilities 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.
