What to do if fingerprint authentication suddenly fails on Suprema Gateway?
- CChristina HernandezAug 12, 2025
If fingerprint authentication suddenly fails on your Suprema Gateway, first, check if your finger or the fingerprint sensor is dirty with sweat, water, or dust. If so, wipe them clean. If that doesn't work, dry both your finger and the sensor with a towel and try again. For overly dry fingers, blow on your finger before attempting authentication again.
