How do fingerprint scanners identify individuals so quickly?

Описание: Fingerprint scanners use optical, capacitive, or ultrasonic technology to capture unique fingerprint patterns. Optical scanners use a light source and sensor to create a digital image of ridges and valleys. Capacitive scanners detect electrical differences between these features, creating a detailed map. Ultrasonic scanners emit high-frequency sound waves to penetrate the skin's surface and capture a 3D representation of the fingerprint. The collected data is processed by an algorithm that compares it to stored templates for authentication. This process, aided by powerful processors, ensures identification within seconds.
