System and method of capturing and producing biometric-matching quality fingerprints and other types of dactylographic images with a mobile device

A non-powered optical module to acquire a dactylographic image comprising:

• a holder to attach the optical module to a location proximate to a camera lens of a camera of a smartphone;
• a housing including a side with an aperture formed therein, and a window framing a transparent surface to contact a skin surface of a person;
• a lighting mechanism to provide light to illuminate the skin surface of the person when the skin surface is placed upon the transparent surface;
• a prism having:
• a first side facing the lighting mechanism,
• a second side facing the window, and
• a 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 camera.
