Precautions for using fingerprint
authentication
Precautions for using fingerprint authentication are as follows:
･
This function is used to authenticate the information on the
characteristics of fingerprint image. For this reason, user
with fingerprint that does not provide enough
characteristics information may not be able to use the
fingerprint authentication.
･
Scanning 3 times or more with the same finger is needed to
register your fingerprint. Do not use different fingers to
register.
･
Authentication performance (the probability of successful
fingerprint authentication for correct sliding of the finger)
depends on the condition of use. The following finger
conditions may make fingerprint registration difficult or
reduce the authentication performance. Taking measures
according to the condition of your finger including washing
hands, wiping hands, using a different finger for fingerprint
authentication, etc. may improve the authentication
performance.
- Finger is wrinkled after taking a bath etc., wet or sweaty
- Finger is sweaty or oily enough to obscure ridges of
fingertip, or is soiled with dirt or oil
- Rough or damaged (cut, inflamed, etc.)
- Extremely dry or having tendency to get dry
- Became fat or thin to cause the fingerprint to change
- Fingerprint unclear by wearing away
- Surface in a condition extremely different from that at the
time of fingerprint registration
