How do scientists match a fingerprint to a specific person?

Each fingerprint is unique. But everyone has a different fingerprint

Each finger print is unique. Everyone has a different finger print, no two are the same. They scan your finger print and put it into a system usually on a computer. The computer then searches the finger print from recent paper worth or birth certificates. The system matches the unique finger print to its owner! The ridges and lines on your finger, or thumb, make it unique.
