“Fingerprints” are the small, unique patterns of lines on the tips of your fingers. No two people have exactly the same fingerprints, which is why they are often used to identify someone.
In daily life, people usually hear “fingerprints” when talking about police work, phone security, or identity checks. For example, a phone may use your fingerprint to unlock, or police may collect fingerprints to find out who touched something.
