Why is fingerprint authentication not working on my suprema BioStation L2 Touch terminals?

If fingerprint authentication suddenly fails on your Suprema Touch terminal, first check the finger and the fingerprint sensor for any sweat, water, or dust. Wipe them clean. If that doesn't work, dry both your finger and the sensor with a towel and try again. If your finger is too dry, try breathing on it before attempting authentication.
