What is a fingerprint?

Your fingerprint refers to the lines and ridges that run up, down, and around each of your fingers you'll be able to see them if you look closely at the bottom side of any of your fingers! One of the coolest things about your fingerprint is that no two people in the entire world have the same fingerprint even identical twins have different fingerprints from each other!!

Because of this, fingerprints are sometimes used to help identify people and tell them apart from one another. Your fingerprint stays the same your whole life and it cannot be changed, so by using a fingerprint, only you can be identified as you!
