Why do people leave fingerprints?

Fingerprints are made of an arrangement of ridges, called friction ridges. Each ridge contains pores, which are attached to sweat glands under the skin. You leave fingerprints on glasses, tables and just about anything else you touch because of this sweat.

How many methods are there for fingerprinting?

Although there are hundreds of reported techniques for fingerprint detection, many of these are only of academic interest and there are only around 20 really effective methods which are currently in use in the more advanced fingerprint laboratories around the world.

What are the characteristics of fingerprints?

Fingerprints consist of ridges, which are the raised lines, and furrows, which are the valleys between those lines. And it’s the pattern of those ridges and furrows that are different for everyone. The patterns of the ridges are what is imprinted on a surface when your finger touches it.
