Fingers and palms can be optically scanned to produce optical finger or optical palm prints by using one or more flexible imaging members in contact therewith. The palm or finger being scanned is positioned on one side of the flexible imaging member and in contact therewith. One or more optical scanners is positioned on the other side of the imaging member. The sensor(s) then sense incident radiant energy or light indicative of friction ridge patterns and minutiae on the respective finger and/or palm. Alternately, RF or electro-static sensing could be used.
