Fingerprint authentication function
Fingerprint authentication is an authentication sliding your
finger over the fingerprint sensor.
❖
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
･
For registration/authentication of your fingerprint, align the
first joint of one of your fingers to the center of the sensor,
press your finger parallel to the sensor and slide it
downward until it passes the fingerprint sensor area. To
prevent authentication failure due to difference in finger
positions at registration and authentication, keep your finger
parallel to the terminal as you slide it.
･
If the sliding movement is too fast or too slow, the
fingerprint may not be correctly recognized.
･
Registration/Authentication of fingerprint may be difficult
with your thumb as the center of the whorl of the fingerprint
may be displaced or distorted. Try as much as possible to
slide your finger so that the center of the whorl of the
fingerprint passes the center of the fingerprint sensor.
･
If the fingerprint is not correctly read, a warning message
appears.
･
If fingerprint registration or authentication is started with the
finger put on the fingerprint sensor, activation may be
unavailable. Put the finger off from the fingerprint sensor
and retry the operation.
･
When connecting the terminal using a USB cable to a device
which requires grounding such as a desktop PC, make sure
that the device is grounded in advance. If the connected
device is not grounded, fingerprint authentication may be
unavailable. In that case, remove the terminal from the
device and then perform fingerprint authentication.
･
Fingerprint authentication technology does not guarantee
complete identity authentication or verification. Note that
