What device is used in the facility access control procedure for identification purposes?

The Common Access Card (CAC) serves as a primary identification tool in facility access control procedures, particularly within governmental and military installations. This card is government-issued and incorporates advanced technology, including a microchip that stores personal data, photograph, and security credentials. As a multifactor authentication tool, it not only verifies identity through the physical card but also integrates with electronic systems to control access to secure areas.

The CAC is specifically designed to meet stringent security requirements, making it a reliable option for controlling access in sensitive environments. It is widely recognized and accepted across various military and governmental sites, ensuring consistent security practices.

While employee ID badges, fingerprint scanners, and access codes have their roles in access control, they may not implement the same level of multifactor security provided by the CAC. Employee ID badges are often less secure, as they can be easily replicated. Fingerprint scanners are useful for biometric verification but require additional technology and integration into systems. Access codes can provide a means of entry but are susceptible to sharing and guessing, which can compromise security. The CAC's combination of identity verification and access control makes it the best answer for identification purposes in this context.
