Abstract
Systems, devices and methods for providing rolled fingerprint capture and palm capture capability in a device having reduced size are provided. In certain embodiments, the systems and methods provide capture of rolled fingerprints, slap fingerprints and palm prints in one continuous workflow in a compact device. In certain embodiments, moisture discriminating optics and/or enhanced definition image formation previously achieved only in devices designed for capturing only fingerprints are provided. In certain embodiments, the systems employ a single scanning device to capture 500 ppi and/or 1000 ppi palm and fingerprint images.
