What are examples of physical biometric devices?

A physical biometric device uses physical identifiers to digitally grant a user or employee at a company access to systems, devices, or data. Examples of physical biometric devices include voice recognition, retina (eye) scanning, fingerprint scanning, and facial recognition (face scanning).

Cybersecurity is focused on preventing unauthorized access to cyber criminals, and the use of biometrics provides the extra security that traditional passwords can no longer provide. On the BEC section of the CPA exam, you might see a question about how a company can prevent unauthorized access to certain systems within an organization.

Another type of biometric security is based on behavioral identifiers, but it is not widely adopted like physical biometric devices are.
