Why is fingerprint authentication not working on my Suprema IP Access Controller?
- JJason ChristianAug 14, 2025
Fingerprint authentication might fail due to several reasons: * Your finger or the fingerprint sensor may be dirty (sweat, water, or dust). Clean both. * Your finger or the sensor might be too wet. Wipe them with a dry towel and try again. * Your finger might be too dry. Blow on your finger and try again.
