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.
Police officers find FINGERPRINTS and everyone has different fingerprints so it is pretty smart of polices.

use fingerprints
Officials use a process called "fingerprinting" to record fingerprints. This is done by inking the fingers and rolling them onto a special card or electronically scanning them using a digital fingerprint scanner. The captured fingerprints are then analyzed and stored in a database for identification and comparison purposes.

i dont no
Fingerprints are unique to each individual and can be used to identify a person regardless of where they are from. Police officers can match fingerprints found at a crime scene to fingerprints in a database to identify potential suspects. This method is highly reliable and widely used in forensic investigations.
