FAQs
Why is my Marks 175 BIO Series Biometric Fingerprint Reader unable to recognize my fingerprint?
The physical condition of the skin on your fingertips directly affects the ability of the reader to recognize the fingerprint. If the skin is damaged or unclear, the print may not always be recognized. We recommend the use of a different finger, or if the readings are inconsistent, you may consider issuing the user a metal key for the lockset.
If a fingerprint is too dry, breathe on the fingertip before attempting authentication.
For children, it may be tricky or impossible to use the reader because their fingerprints are often too small or unclear. If a child will be using the 175 BIO, we recommend registering their fingerprints every six months.
For the elderly, their fingerprints often contain too many fine lines, and therefore may prove to be difficult or impossible to register.
For particularly problematic users, we recommend registering multiple fingerprints on the same hand.
