摘要

A fingerprint matching device has a CPU (120) that registers in a RAM (140) registration fingerprint images of a plurality of portions of a finger of a person to be registered, calculates the relative positions of the registration fingerprint images, allows an image sensor (170) to read a part of the finger of the person to be matched as a read fingerprint image, satisfies a specific fingerprint image out of the registration fingerprint images on the basis of the relative positions, and conducts fingerprint check according to the degree of agreement between the specified registration fingerprint image and the read fingerprint image.
