Automated fingerprint identification systems (AFIS) are primarily used by law enforcement agencies for criminal identification purposes, the most important of which is the identification of a person suspected of committing a crime or linking a suspect to other unsolved crimes.

What are the two advantages of AFIS?

• Fingers to search and rules of use.
• Case priorities.

• System upgrades and new technology.
• Service and maintenance.

How does AFIS help solve crimes?

The AFIS database also contains more than 12,000 unidentified fingerprints left at crime scenes and on items of evidence.
