Fingerprint analysis

• A person’s fingerprints do not change over time.
• In addition, fingerprints are unique to an individual. Even identical twins have different fingerprints.
• There are THREE types of fingerprints that can be found: Latent, Patent, and Plastic
• Latent fingerprints - Made from the sweat and oil on the skin’s surface. Are invisible to the naked eye and require chemicals to see.
• Patent fingerprint - Made by blood, grease, ink or dirt, easily visible to the human eye
• Plastic fingerprints - These are three-dimensional, can be made by pressing your finger in fresh paint, wax, soap or tar.

  These can be easily seen by the naked eye
• There are three fingerprint class types: Arches, Loops and Whorls
