Abstract
A card type device is mounted on a card slot of an electronic appliance. A transparent cylindrical-shaped roller is provided at an edge portion of a housing such that an outer peripheral plane of the roller is projected from the edge portion. A one-dimensional image sensor is provided inside the roller, which acquires one-dimensional fingerprint data of a finger of a user, and this fingerabuts against the outer peripheral plane of the roller. Since the finger abutting against the outer peripheral plane of the roller is moved, the roller is rotated, so that one-dimensional fingerprint data which are continuously acquired by the one-dimensional image sensor are synthesized with each other to produce fingerprint data as a two-dimensional image. The synthesized fingerprint data is transmitted to the electronic appliance which carries out fingerprint identification.
