An Automated Fingerprint Identification System (AFIS) is a sophisticated biometric technology designed to capture, store, analyze, and match fingerprint data for identification and verification purposes. It plays a critical role in modern security infrastructure, particularly in law enforcement, border control, and civil identification systems.
The functioning of an AFIS begins with fingerprint acquisition, which can be done through ink-based methods or, more commonly today, via digital scanners. These scanners capture high-resolution images of the fingerprint, focusing on key features such as ridges, valleys, and minutiae points.
