How should antipassback portals be configured to accurately track individuals using a credential?

The configuration of antipassback portals is crucial for ensuring that system accurately tracks individuals using their credentials. When configured for card entry/card exit, the system enforces that an individual must use their credential to enter and then also must use it again to exit the controlled area. This setup ensures accountability and prevents credential sharing or misuse, as each individual's entry and exit are recorded accurately in the system.

In a card entry/card exit configuration, if an individual attempts to enter without first exiting, or vice versa, the system can identify that the protocol has not been followed, thus maintaining the integrity of access control. This is particularly important in high-security environments where knowing who is in or out at any given time is critical.

Other configurations, such as open access or continuous access, do not provide the same level of tracking since they do not require credential verification for exit, which can lead to unauthorized access and potential security breaches. Single entry may also limit tracking capabilities by not ensuring a reliable check-in process for individuals leaving the area. Therefore, the card entry/card exit arrangement is the most effective for maintaining precise oversight of credentialed access.
