Automated Fingerprint Identification System (AFIS)

One of the latest innovations in crime analysis is the Automated Fingerprint Identification System (AFIS), which is a computerized system that stores the identifying characteristics of more than 4.8 million individuals currently on file in the DPS Crime Records Service. The AFIS Section also performs systematic computer searches of unknown fingerprints by optically scanning a print and comparing it with those on file. Prior to AFIS, fingerprint searches had to be done manually, making it an impractical, time-consuming process to compare an unknown print to the millions of known prints on file. Latent AFIS personnel also provide training for the other latent AFIS operators across Texas.
