Automated Fingerprint Identification System (AFIS) technology is used in a
variety of law enforcement and civil applications. In law enforcement,
fingerprints are collected from arrested subjects and searched against
local, state, regional, and/or national fingerprint databases. The subject's
ten fingerprints are acquired either through the traditional ink-and-roll
method or through an optical livescan system, consisting of a sizeable
fingerprint scanner, PC, and imaging and transmission software.
