What is a CAC Card?

CAC Cards, or Common Access Cards, are smart identification cards issued by the U.S. Department of Defense to military personnel, civilian employees, and eligible contractors. They serve as both a physical ID and an access card for secure facilities, computer networks, and other DoD resources. The embedded microchip stores personal information and security certificates, enabling secure authentication and encryption for digital communications. CAC Cards are essential for verifying identity and controlling access to sensitive areas and information in military and government operations.
