Fingerprint Scanner

A fingerprint scanner is a biometric device used to verify a person's identity by scanning their unique fingerprint patterns. It works by capturing an image of the fingerprint, then analyzing the ridges and valleys that form the distinct pattern. This data is compared to pre-registered fingerprints in a database. Fingerprint scanners are commonly used for security purposes in smartphones, laptops, access control systems, and other devices. They offer a convenient, secure, and reliable way to authenticate users since each fingerprint is unique and difficult to duplicate. Fingerprint scanners come in various types, including optical, capacitive, and ultrasonic, each using different technology to capture the fingerprint image.
