Police could use black powder.
I do not think that there is really a purpose of making fingerprints not on purpose anyways. Fingerprints are mostly made because of the oil of our fingers. Answer 2: Assuming you mean why is is that some agencies take your fingerprint (police, CBP...). Its because each individual has its own unique fingerprint mening that is you have someone fingerprint you can identify him. In most crimes fingerprints are left behind and these can be collected and matched with fingerprints on database to identify the suspect.
No - fingerprints are set at the time of birth. However, you can try to remove them (an extremely painful process).
It is generally not possible to change your fingerprints. Fingerprints are unique to each individual and are determined by genetic factors. Attempting to alter or change your fingerprints is a complex process and may not be successful.
No, each hand has a unique set of fingerprints. Even the fingerprints on each individual finger of the same hand are different. This uniqueness is what makes fingerprints a reliable form of identification.
Yes, twins have different fingerprints. Even identical twins, who share the same DNA, have unique fingerprints because fingerprints are formed randomly in the womb due to factors like pressure and environment.
They have data bases which are used and stored for information
Fingerprints left at a crime scene are called latent prints. These prints can be collected and used as evidence to help identify suspects and link them to the crime.
If fingerprints remain they must be collected with an adequate substance, as ninhydrin.
Fingerprints can be collected using techniques like cyanoacrylate fuming, which involves exposing the print to cyanoacrylate vapors to make it visible, or using ninhydrin to react with amino acids in the print and produce a color change. Another method is using physical or chemical methods to develop prints in substances like blood or grease.
Fingerprint powder is a fine powder commonly used by forensic investigators to develop and visualize fingerprints left at a crime scene. It adheres to the oils and residues left behind by the ridges of the fingers, making the fingerprints visible and allowing them to be collected as evidence.

People have always had fingerprints. Also, everyones fingerprints are diffrent.
None of a child's fingerprints will match his or her mother's fingerprints. Each individual has different fingerprints. Even identical twins have different fingerprints.
Fingerprints can be collected using fingerprint powder, which is dusted over the surface where prints are suspected, lifted with tape, and transferred to a card. Alternatively, investigators can use a technique called cyanoacrylate fuming, where superglue fumes are used to develop prints on non-porous surfaces.
There are 8 tipes of fingerprints
latent fingerprints
The koala is the only animal with distinctive and unique fingerprints. The fingerprints are very similar to that of humans in that they are comprised of patterns, but the trained eye can distinguish them quite easily from human fingerprints.
