The Integrated Automated Fingerprint Identification System (IAFIS) is a national fingerprint and criminal history database maintained by the FBI. It allows law enforcement agencies to quickly identify individuals by comparing their fingerprints against a vast database of known prints. This system enhances the efficiency of criminal investigations and helps in solving cases more effectively. IAFIS contains millions of fingerprint records, including those from criminal offenders, civil applicants, and latent prints collected from crime scenes. The system uses advanced technology to analyze and match fingerprints, providing law enforcement with critical information to aid in public safety and crime prevention efforts.
