Which of the following methods of authentication is considered a form of biometric security?
Badge reader
Key fobs
Fingerprint scanner
Magnetometers
A biometric security method uses physical characteristics to identify and authenticate an individual. Fingerprint scanners use the unique patterns of a person's fingerprint for identification, making them a common biometric security measure. Badge readers rely on a physical or digital token rather than biometric data. Key fobs provide access based on a physical device that the user carries and do not involve biometric data. Magnetometers detect metal but do not ascertain an individual's identity.
