What type of access control system includes a common access card?

The correct answer is that an automated electronic system is the type of access control system that utilizes a common access card (CAC). This system leverages technology to manage and restrict access to facilities or information systems based on the credentials presented by an individual. The CAC typically contains embedded chip technology that allows for secure authentication through electronic readers.

Automated electronic systems offer enhanced security and efficiency compared to other methods, as they can quickly process access requests, log entry and exit times, and integrate with other security measures like surveillance cameras or alarm systems. The use of a common access card ensures that only authorized personnel can gain entry, while also facilitating rapid and convenient access for users.

Other types of access control systems, such as manual systems, rely on physical means to control access (like locks and keys), which are less secure and efficient. Biometric systems rely solely on unique physical characteristics for authentication, and while they are secure, they do not typically use common access cards. Lastly, paper-based security systems are outdated and lack the speed and security features of automated electronic options.
