What are fingerprints and fingerscans used for?
Fingerprints are used in forensic applications: large scale, one-to-many searches on databases of up to millions of fingerprints. These searches can be done within only a few hours, a tribute to the computational power of AFIS. AFIS (Automated Fingerprint Identification Systems) is a term applied to large scale, one-to-many searches. Although finger-scan technology can be used in AFIS on 100,000 person databases, it is much more frequently used for one-to-one verification within 1-3 seconds.
