An automatic finger guide for fingerprint scanners includes active scan area
on
the scanner surface upon which one finger rests and a non-active scan area on the
scanner surface on which the other finger(s) rest to provide stability, a stop
post to indicate how far forward to place the hand, a guide post to assist in positioning
the finger left to right or right to left as the case may be, sensors on the post
to provide feedback to the user to when the hand is properly in place and to determine
the position as to where the finger comes to rest on the active scan area.
