What is the term used when multiple persons enter via a single access granted transaction?

The term that describes the situation when multiple individuals enter through a single access granted transaction is known as piggybacking. This occurs when one person takes advantage of another person's legitimate access to gain entry into a secure area without proper authorization.

In the context of electronic access control, piggybacking poses security risks, as it compromises the integrity of access control systems designed to ensure that only authorized individuals enter specific locations. To differentiate from other terms, tailgating typically refers to a similar unauthorized entry but emphasizes the close physical following behind someone who has legitimate access. Group entry and double access aren’t commonly recognized terms within the context of access control and security, making them less applicable in this scenario. Understanding the correct terminology reinforces awareness of security practices and the importance of maintaining strict access controls.
