The fingerprint is considered a key element in a crime or investigation scene. This unique identifier of each person can confirm to the investigators the presence of the suspect on the analyzed scene. This obviously requires fingerprint detection by a forensic scientist and their treatment in the laboratory to associate an identity to each. This procedure takes a longer or shorter time that may be valuable in critical cases of terrorism and organized crime. In this context, and in order to help investigators better analyze the scenes, we thought about designing and manufacturing a portable system for the acquisition, analysis and processing of fingerprints on a crime scene in order to know the identities of the suspects in real time.
