Signs of Fingerprints 

Signs are typically visual or auditory cues that convey meaning or information. Signs can take many different forms, including physical gestures, symbols, words, and sounds. For example, a stop sign is a physical sign that tells drivers to stop their vehicles before proceeding.

Fingerprints are unique patterns of ridges and valleys on the tips of our fingers. No two people have the same fingerprints, which makes them useful for identifying individuals. Fingerprint analysis is a common method of forensic identification used by law enforcement agencies around the world.
