Footprint, mark or trace that a person leaves on the ground
A footprint is the mark or trace that a person leaves on the ground or on some road when stepping on it. Generally, the earth, grass, and other materials such as wet cement are capable of containing in a very definite way the footprint of the person or animal that passed through there.
Those marks that our hands leave on some surface when touched
Meanwhile, with regard to handprints, fingerprints or also called fingerprints, we must clarify in principle that both concepts refer to the same thing, they are those that just leave our hands and fingers on some surface when touched.
It is more precisely a visible impression that the papillary ridges of the fingers of the hand know how to leave on any surface.
Through them a person can be identified. Unique and non-transferable
The importance of fingerprints and fingerprints lies in the fact that it is through them that a person can be identified. There is nothing more personal and individual than the marks left by our fingers, it is unique and non-transferable and that is why they are used as a way to unequivocally identify an individual. That is, a person's fingerprints are taken and they will only correspond to that individual, they can never be attributed to another.
They accompany identifications in identity documents and passports
When people manage identity documents or other documentation of the style before competent authorities, such as identity cards and passports, fingerprints are taken so that such impressions accompany our identification.
Until the advent of technology, the organisms that issued identity documents and other identifications took the prints of each finger through a substance that allowed a clear representation of the capillary of the fingers. Today, with the increasingly present technology, less messy and cumbersome methods are used to take them, such as specialized appliances.
Meanwhile, if a situation occurs that at first glance does not allow a person to be identified, as sometimes happens in accidents, when fingerprints are taken, the identification of that person can be established.
Crucial in procedures that investigate crimes or illicit
On the other hand, at the instigation of a crime or illicit, the first thing the security forces do is take impressions of the place to detect the presence of some of these traces, which later will allow them to determine the people who were present there and probably identify the aggressor or perpetrator.
