A device that identifies a person using a fingerprint or face belongs to which category?

Answer and explanation

Correct answer: Biometric input device

The governing concept is biometric authentication, in which a computer captures a measurable and distinctive human characteristic. A fingerprint or face scanner collects this feature as input and compares it with stored reference data, so option D is correct. An output device presents results, a storage device saves data, and a cooling device controls temperature. Those categories do not describe identity capture.
