Which security control best describes installing badge readers on data-center doors to allow entry based on job role?

Installing badge readers on data-center doors to restrict entry based on job role is a classic example of physical access control. This control method governs who can physically enter a specific location or access a tangible asset. While the badge system might use role-based access control (RBAC) internally to determine who gets access, the primary control being implemented at the door is physical. Biometrics involves unique biological characteristics (like fingerprints or retina scans), which aren't explicitly mentioned here, though a badge system could incorporate them. Multifactor authentication (MFA) requires two or more distinct authentication factors, typically used for logical access, not purely physical entry as described.
