Fingerprints

Fingerprints can identify us and only us. Everyone's fingerprints are different; there are no two alike. That's why they prove so useful when identifying dead bodies or fingerprints at a crime scene. Police use them at crime scenes; banks use them to identify checks. There are so many different uses for fingerprints.

Fingerprints are read by using special kits made for reading every ridge on your finger. DNA specialists are specially trained to read fingerprints. Fingerprints are found by putting dust over them so the ridges stand out then they copy them on to a sticky piece of transparent paper.

Pre-historic picture writing of a hand with ridge patterns was discovered in Nova Scotia. In ancient Babylon, fingerprints were used on clay tablets for business transactions. In ancient China, thumbprints were found on clay seals. In 14th century Persia, various official government papers had fingerprints, and one government official, a doctor, observed that no two fingerprints were exactly alike.

Fingerprints have many uses as said in the first paragraph. Police use fingerprints when a crime is committed. They take the fingerprint and compare it to other prints on file to find out who committed the crime. Other uses for fingerprints are to verify checks at banks. The most recent use is for child safety they can get an identification card from the state patrol with their name and address it also has their fingerprint on it.
