Yes, access control systems can assist in preventing and detecting tailgating – where an unauthorised person follows an authorised person through a secured door – by tracking individual access events, though complete prevention relies on layered security. In the United States, these systems operate under the framework of OSHA regulations and state-level workplace safety laws, requiring employers to maintain a safe working environment, which includes controlling access.
As of December 2025, most modern access control systems utilise credential readers (card, fob, biometric) linked to a central database. Each access event is time-stamped and associated with a specific individual. Advanced systems now include anti-passback features, preventing a single credential from being used for multiple entries without re-authentication. Software platforms routinely generate reports detailing access logs, allowing security personnel to review for anomalies – such as two entries occurring within a timeframe too short for a single person to pass through legitimately. Data retention policies, influenced by regulations like CCPA in California or similar state laws, dictate how long these records must be stored. Integration with video surveillance systems is common, providing visual verification of access events. Australian systems operate under similar principles, guided by WHS legislation and PCBU obligations, with data handling governed by Australian privacy principles.
Effectively, access control systems create an audit trail of who accessed which door and when, enabling post-incident investigation and contributing to a safer, more secure environment.
