How does fingerprint recognition work?

Fingerprint recognition works by capturing an individual's fingerprint image using a sensor. The sensor then analyzes the unique patterns and ridges present in the fingerprint, such as ridge endings, bifurcations, and ridge counts. These patterns are converted into a digital template, which is stored in a database for future comparison. When a person wants to authenticate their identity, their fingerprint is again captured and compared with the stored template. If the patterns match within a certain threshold, the person is granted access or verified.
