Using fingerprint authentication
Fingerprint authentication is an authentication
sliding your finger over the fingerprint sensor.
■ Precautions for using fingerprint
authentication
• This function is designed to authenticate using
the characteristics information 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 several times 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
correctly holding down your finger) depends on
usage conditions. Fingerprint registration may
be difficult or the authentication performance
may decrease depending on conditions such as
the hand is dry. 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.
• When registering or authenticating your
fingerprint, align the first joint of one of your
fingers to the center of the sensor, and hold
down your finger. To prevent authentication
failure due to difference in finger positions
at registration and authentication, keep your
finger parallel to the terminal as you place it.
