What is fingerprints?
A fingerprint is an imprint made by the
pattern of ridges on the pad of a human
finger.
Fingerprints are commonly believed to
provide traction for grasping objects. These
prints are often left on objects at a crime
scene and are therefore used in forensic
science to identify suspects.

Fingerprint history
In 1904
The use of fingerprints began in
Leavenworth Federal Penitentiary in
Kansas, and the St. Louis Police
Department. They were assisted by a
Sergeant from Scotland Yard who had
been on duty at the St. Louis Exposition
guarding the British Display.
Why fingerprint identification?
Fingerprints offer an infallible means of
personal identification. That is the
essential explanation for their having
supplanted other methods of
establishing the identities of criminals
reluctant to admit previous arrests.
Other personal characteristics change -
fingerprints do not.
