An individual attempts to replicate an employee’s staff pass using specialized equipment. Which measure provides the strongest deterrent against duplication?
Restrict entry for those without a designated uniform color
Add a laminate overlay that displays a staff photo on the pass
Integrate a database lookup to confirm pass data upon each entry
Use credentials that change key data whenever they are presented
Credentials that change key data introduce a new handshake each time they are used. This disrupts anyone who seeks to capture and duplicate a single, static signal. A laminate overlay is a visual deterrent that can be replicated with high-resolution printing. Granting entry based on uniform color ignores the pass’s authenticity. External database lookup alone does not stop the pass from being copied if the stored data is captured once.
