About Fingerprints

Fingerprint technology uses a persons fingerprints to identify him through fingerprint scanning. This technology is used not only in security systems, but also in the field of forensic science and crime scene investigations. It can even be found on gadgets found in the home, such as certain laptop computers.

Each individual has a different set of fingerprints from every other individual in the world. This is often referred to as a biometric fingerprint. Biometrics is the study of how humans differ from each other based on biological factors, such as how each persons fingerprints form differently. Even identical twins do not share the exact same set of fingerprints. A persons fingerprints are like an identification card.

To use a fingerprint scanner, the person places his hand or finger onto the scanner. The machine then scans the fingertips to generate a picture of the tiny lines and ridges that make up the fingerprint. It puts together a detailed image of this fingerprint and stores it for later use. The fingerprint is connected to the name of the person for future reference.
