Finger guide device with switch

Abstract

A finger guide device that positions a finger (or minutiae containing digit) of a human subject on a fingerprint sensor in a manner optimal for the data capture operation of authentication of identification of said subject, wherein a relevant portion of the finger is in alignment with a sensor or scanner. The finger guide device may also be used for enrollment of the initial fingerprint data into the system. The device may contain an outer surface ridge which feels somewhat uncomfortable due to application of a high pressure per square inch on small areas of the finger when the finger is incorrectly positioned to encourage correct placement of the finger. The finger guide device may have a curved inside surface to contour to a wide variety of fingertip shapes and sizes, wherein the sides and front have shorter radii of curvature than the rearward portion of the finger guide device

1 . A finger guide device for mounting in alignment with a fingerprint sensor comprising
 a concave circular or oval surface having a bottom with an opening in the bottom to expose a fingerprint sensor that can be placed in the opening, the surface having a fingertip end, finger sides and a first joint end, the periphery of the surface being substantially in one plane,   wherein the finger guide device is in communication with a switching means to permit the finger guide device to serve as an element in a switch.   
     
     
         2 . A finger guide device as claimed in  claim 1  wherein the concave surface is circular. 
     
     
         3 . A finger guide device as claimed in  claim 1  further comprising a mechanical movement feedback mechanism to provide feedback information to a user's finger.
