Fingerprints have been used as a means of identification for more than 100 years and are unique to every individual.

Fingerprints are made up of an intricate system of ridges which creates an uneven surface on the palms of the hand and soles of the feet. The Fingerprint Examiner and Tenprint Identification Officer (TIO) use the arrangement of the ridges and their certain unique properties to make the identification.

This section will help you to understand how fingerprints develop and the processes used to provide verification of identity.
