What is finger impression?

A finger impression, also known as a fingerprint, is an impression made by the unique patterns of ridges and grooves on the surface of a person's fingertip. These patterns are formed during fetal development and are specific to each individual, making fingerprints a reliable means of identification. Finger impressions are commonly used in forensic science, security systems, and biometric identification technologies. They can be collected using ink, digital scanners, or other methods for various applications.
