Types of Fingerprints :

In this experiment, you match the prints collected from the scene with the fingerprints of the culprits. One of the methods to do that is by matching the type of fingerprints.

The types of fingerprints are:

  • Loop: It must have one or more ridges entering from one side of the print, curving and exiting from the same side. Types of loop are: left loop and right loop.
  • Whorl:  Whorls must have at least one ridge that makes a complete circuit.
  • Arches: Arch ridges tend to enter from one side of the print and leave out the other side.

There are two types of arches plain arch and tented arch.
