• A triangular ridge pattern created when ridge patterns diverge

Ridge circle created when ridge patterns diverge

An impression left on any surface that consists of patterns made by the ridges on a finger

Impressions left on the air

IAFIS

FBI-developed national database of more than 76 million criminal fingerprints and criminal histories

88 million criminal fingerprints

• a concealed fingerprint that is made visible through the use of powders or forensic techniques

• 

A center of a loop

The use of powders of forensic science

Arch fingers

• A fingerprint pattern in which the ridge pattern flows inward and returns in the direction of the origin

Fingerprint pattern which the Ridge pattern sinks outward

• combination of details and positions of ridges that make it unique

Finger

• The combination of details in the shapes and positions of ridges in fingerprints that makes each unique; also called ridge characteristics

A surface that transforms their print

• a non-visible fingerprint produced when fingers coated with blood, ink, or some other substance touch a surface and transfer their print

• a visible fingerprint produced when fingers coated with blood, ink, or some other substance touch a surface and transfer their print to that surface

• 

A center of a loop

• A three-dimensional fingerprint made in soft material such as clay, soap, or putty

• 

A concealed fingerprint that is visible

• the shape of ridges between the center of a delta and the core of a loop

• the number of ridges between the left of a delta and the core of a loop

• the number of ridges between the center of a delta and the core of a loop

• 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 three categories: arches, loops, and whorls. They are also visible on the soles of feet and bottoms of toes

• 

• the recognizable shape of the ridges found in the end pads of fingers that form lines on the surfaces of objects in a fingerprint.

They fall into three categories: circles, loops, and lines. They are also visible on the soles of feet and bottoms of toes

• 

• the recognizable pattern of the ridges found in the beginning pads of fingers that form lines on the surfaces of objects in a fingerprint.

They fall into three categories: arches, loops, and whorls. They are also visible on the soles of feet and bottoms of toes
