A fingerprint with ink on a piece of paper

A fingerprint is a trace of a human finger left on a surface. Human fingers have small structures on them (like mountains and valleys). These structures are unique in every human; they can be used as means of identification.

There are many different ways to take fingerprints. Forensic scientists use these techniques to identify a person.

Electronic fingerprint scanners became widespread in the early 21st century.
