Fingerprints is one of the only unique marks of distinction that nature has given to every human being. A fingerprint is the impression made by the papillary ridges on the ends of the fingers and thumbs. Fingerprints afford an infallible means of personal identity, because the ridge arrangement on every finger of every human being is unique and does not alter with growth or age.
Fingerprint is one of the earliest forms of scientific evidence to be recognized by courts of law.
