What is a major issue with standard doors in access control?

The major issue with standard doors in access control is that once opened, entry cannot be controlled. This means that when a standard door is physically opened, it does not have the capability to manage or track who enters or exits afterward. This lack of control can allow unauthorized individuals to gain access to secured areas following the legitimate user. Unlike electronic access control systems, which can ensure that only authorized individuals can gain entry and track access history, standard doors typically do not offer these functionalities. As a result, relying solely on standard doors without additional controls can lead to significant security vulnerabilities in environments where access management is critical.
