    a housing having a side with an aperture formed therein, and a window framing a transparent surface arranged to contact a skin surface of a person;

    a lighting mechanism arranged to provide light to illuminate the skin surface of the person when placed upon the transparent surface;

    a prism having;

    a first side facing the lighting mechanism,a second side facing the window, anda third side through which a dactylographic image of the skin surface of the person exits the prism; and

    a plurality of light reflecting surfaces within the housing spatially separated from the prism, the plurality of light reflecting surfaces disposed within the housing to reflect the dactylographic image of the skin surface of the person exiting the prism towards the aperture in the side of the housing toward lens of the built-in camera.
