Explanation

A retina scanner is a biometric authentication device that reads the unique pattern of blood vessels in a person's retina. Because retina patterns are extremely difficult to replicate or steal, a retina scanner provides the highest level of physical access security for a server room. A one-time password (OTP) is a logical/software control, not a physical access mechanism. Geofencing defines location-based boundaries but does not directly control physical entry. An Access Control List (ACL) is a logical permission system for network or file resources, not a physical security method.
