FPBE W2 Fingerprint Reader
When the fingerprint recognition fails
The ARD-FPBEW2 can recognize a fingerprint regardless of a change of
season or finger condition. However, the authentication rate may vary
according to the external environment or fingerprint input method.
If the fingerprint authentication cannot be done smoothly, it is
recommended to take the following measures:
1. If the finger is smeared with water or sweat, dry off the finger and
then scan the finger.
2. If the finger is too dry, blow your breath on the fingertips and then
scan the finger.
3. If the finger has a cut, register the fingerprint of another finger.
4. The initially registered fingerprint often may have not been scanned
correctly, so register the fingerprint again according to 'Cautions for
enrolling a fingerprint'.
