This paper introduces a novel touchless fingerprint acquisition device for five fingerprints. The device consists of a single CCD camera, a mirror, two LED arrays and a rotational gear. Unlike the conventional touchbased fingerprint sensors, the device acquires a deformation free fingerprint image. Also the device captures five fingerprint images at once. In this paper, the device was evaluated in three ways: the area of valid regions, the rolling degree of a finger, the degree of focus.
