Answer:

A barcode reader scans a barcode that is comm0only found on an item that you would buy from the store, for inventory purposes. A biometric device is something that requires something from the human for a form of identification. Like a fingerprint scanner that can be found on a cash register for employees or face id found on a smartphone.
