The latest evidence suggests that fingerprints process vibrations in the skin to make them easier for nerves to pick-up.

They may seem little more than digital decoration but biomechanics have long known that fingerprints have at least one use: they increase friction, thereby improving grip. There have also been hints that fingerprints play a role in the sensation of touch. One possibility is that when a finger is moved across a surface, each ridge in a fingerprint acts like a tiny lever, magnifying the subsurface strain for the nerve endings beneath.
