Common questions

What did NGI add over IAFIS beyond just fingerprints?+

NGI expanded the repository to include palmprints, iris images, facial images and scars/marks/tattoos (SMT) data alongside ten-prints, and improved fingerprint matching accuracy, letting investigators search across multiple biometric modalities rather than fingerprints alone.

Who can submit searches to NGI, and are the records limited to convicted offenders?+

Authorized federal, state and local law enforcement agencies submit searches through CJIS. The database includes civil records such as background-check and licensing submissions in addition to criminal booking records, so not every entry represents a criminal history.
