How does fingerprint systems work?

Fingerprint systems work by capturing the unique patterns of ridges and valleys on an individual's fingertip using a sensor. When a finger is placed on the sensor, it generates a digital image of the fingerprint, which is then processed to extract distinctive features, such as minutiae points. These features are converted into a mathematical representation and stored in a database. When a fingerprint is scanned for authentication, the system compares the live scan with stored templates to verify identity based on matching patterns.
