Automated Fingerprint Identification System (AFIS)

The introduction of the Automated Fingerprint Identification System (AFIS) in 1997 has allowed fingerprint technicians to scan fingerprint images into a database for easy storage, retrieval, and comparison.

AFIS gives DCI the capability of real-time identification of a suspect
in investigations, based on fingerprints found at the scene of a crime.

The SD DCI expanded the AFIS technology in 1999 by installing Livescan arrest reporting devices in the three largest local law enforcement contributing agencies: Minnehaha, Pennington, and Brown County Sheriff's Offices.  Livescan is a machine which replaces ink-and-roll fingerprints.  Fingers are rolled across a plate and scanned into a computer, then converted to a digital form for storage and transmitted electronically to the DCI workstation for identification.  Fingerprint cards can be printed out on a laser printer at the local and state sites.

A store and forward server/archive was installed in the ID section to enable processing and storing of these Livescan transmittals.  This equipment will be used in the future to connect to the FBI's Integrated AFIS whereby arrest reporting will be electronically submitted, replacing the mailed paper arrest cards.  

In 2001 and 2002, Livescan technology was implemented in seven more law enforcement agencies: Hughes, Davison, Yankton, Codington, Meade, Brookings and Lawrence County Sheriff's Offices.  All are operational and over 70% of SD's arrests are reported in a paperless environment.
