Why fingerprint recognition is not working on my Suprema Touch terminals?

If fingerprint recognition isn't working on your Suprema Touch terminals, check for sweat, water, or dust on your finger or the fingerprint sensor and wipe it clean. If that doesn't work, try again after drying both with a dry cloth. If your finger is too dry, try blowing on it gently before attempting again.
