It’s the most annoying thing when your fingerprint scanner just won’t work. It stops taking fingerprints and sits there doing nothing.
The most common mistake that users make is not maintaining and cleaning their scanner properly. Here are a few simple tips from Chiral Software, a Cebu, Philippines based supplier of biometrics, including fingerprint scanners and the Megamatcher license system.
How to Clean:
To clean the Fingerprint Reader window, apply the sticky side of a piece of adhesive cellophane tape on the window and then peel it away.
Under heavy usage, the coating on the Fingerprint Reader window may turn cloudy from the salt in perspiration. In this case, gently wipe the window with a cloth that is dampened with a mild ammonia-based glass cleaner. Do not use paper products to clean the window.
Again to emphasize: DO NOT use alcohol or any alcohol based cleaner and DO NOT use paper products such as tissue to clean the window.
