4. Matching Score is output when
authentication attempted. It is a result
of matching an input fingerprint with
existing fingerprint data. The score
range is 0 ~ 9. The score is compared
with the security level value of the
General tab, determining success or
failure. If the security level is 5 and
the matching score is lower than 5,
verification fails. If the score is
higher than 5, on the other hand,
verification is passed. If a fingerprint
input is too dry or to wet or it is not
properly input, the score can turn out
to be low.
