  2. Arch– fingerprint pattern in which the ridge pattern originates from one side of the print and continuers to the other side • Core – center of a loop • Delta– a triangular ridge pattern • Fingerprint – an impression left on any surface that consists of patterns made by the ridges on a finger

  3. IAFIS (Integrated Automated Fingerprint Identification System) – FBI – developed national data base of more than 76 million criminal fingerprints • Loop – a fingerprint pattern in which the ridge pattern flows inward and returns in the direction of the origin • Patent fingerprint – a visible fingerprint produced when fingers coated with blood, ink, or some other substance touch a surface and transfer their print to that surface

  4. Plastic fingerprint – a three-dimensional fingerprint made in soft material such as clay, soap, or putty • Ridge characteristics (minutiae) – the combination of details in the shapes and positions of ridges in fingerprints that makes each unique • Ridge count – the number of ridges between the center of a delta and the core of a loop

  5. 11. Ridge pattern – the recognizable pattern of the ridges found in the end pads of fingers that form lines on the surfaces of objects in a fingerprint. They fall into 3 categories: arches, loops, and whorls 12. Ten card – a form used to record and preserve person’s fingerprints 13. Whorl – a fingerprint pattern that resembles a bull’s eye
