Under what circumstances can the airport revoke an individual's ID card privileges?

The airport has the authority to revoke an individual's ID card privileges at any time if the violation is severe. This means that if a person commits a serious infraction related to security protocols, safety regulations, or any conduct that jeopardizes the integrity of airport operations, the airport can immediately terminate the access granted by the ID card. This approach is crucial for maintaining a safe and secure environment in airport facilities, where adherence to security regulations is paramount. The severity of a violation can warrant immediate action without prior warning, reflecting the airport's commitment to safety and security.

In contrast, the other options suggest limitations or conditions that do not align with the overarching goal of maintaining security and safety. For instance, tying revocation only to the application process, infrequent use of the ID, or requiring a warning prior to revoking privileges does not adequately address situations where immediate action is necessary for the protection of all airport personnel and visitors.
