Your fingerprints are unique. They are yours, and yours alone. They can open doors, unlock your phone, let you into a country, or even just into a theme park. They are your personal identifier. Although there are many uses for fingerprints, perhaps the one which has most captured the public’s imagination is their use in forensic science. After all, how many criminals in stories wouldn’t have been caught without a careless fingerprint left at the scene. Because of this, it is quite fitting that this is also one of its first recorded uses.
