What is it called when multiple persons enter via a single access granted transaction?

The term that describes multiple people entering through a single access granted transaction is known as piggybacking. This occurs when one individual gains entry using an access credential, and additional individuals follow closely behind without presenting their own credentials. This practice raises significant security concerns because it can lead to unauthorized access if the following individuals are not authorized to enter the secured area.

Tailgating often refers specifically to following closely behind an authorized individual without any intent to use an access device or credential, typically to gain entry into a secure area. However, piggybacking implies a conscious effort to take advantage of the valid access granted to another, which is why it is the more precise term in this context.

Understanding this difference is important for maintaining security protocols, as it emphasizes the need for vigilance in monitoring access points and ensuring that all individuals are properly credentialed before entering secure environments.
