MINIATURE CONTACTLESS FINGERPRINTING DEVICE
First Claim
1. A handheld apparatus for contactless acquisition of a fingerprint image, the handheld apparatus comprising:
- an enclosure that includes a hollow finger receiving area sized and shaped to receive a finger; and
at least three digital image capture devices housed within the enclosure and arranged along a circular arc;
each of the digital image capture devices positioned along the circular arc at substantially a same distance from the finger receiving area and positioned along the circular arc to have a respective optical axis that lies at about 45°
to another of the digital image capture devices, wherein the optical axes intersect within the enclosure,each the digital image capture devices operable to acquire a partial fingerprint image of the finger in a contactless manner, each of the partial fingerprint images corresponding to a different side of the finger, such that the acquired fingerprint image, when combined, produce a nail-to-nail fingerprint image.

Abstract
A handheld apparatus for contactless acquisition of a fingerprint image is disclosed. One such apparatus includes an enclosure and at least three digital image capture devices housed within the enclosure and arranged along an arc. The enclosure includes a hollow finger receiving area, sized and shaped to receive a finger. Each of the digital image capture devices is positioned along the arc at substantially a same distance from the finger receiving area and positioned along the arc to have a respective optical axis that lies at about 45° to another of the digital image capture devices. The optical axes intersect within the enclosure. Each digital image capture device is operable to acquire a partial fingerprint image of the finger in a contactless manner. Each partial fingerprint image corresponds to a different side of the finger. The acquired fingerprint images combine to produce a nail-to-nail fingerprint image.
