The selection of always advising employees to swipe their access card at the entrance highlights a critical element of physical security within an organization. By ensuring that employees consistently use their access cards, this tactic helps to establish a secure entry protocol, which can significantly mitigate unauthorized access.

Using access cards creates a barrier that controls who can enter specific areas of the organization. It is a direct method of authentication, confirming that individuals have been granted permission to access certain locations. This practice also allows for better monitoring of who enters and exits the premises, making it easier to identify unauthorized access attempts and trace movements within the organization.

Furthermore, regular swiping of access cards can help in maintaining awareness among employees about the importance of security protocols. This practice fosters a culture of security consciousness within the workplace, as employees become accustomed to following these protocols rigorously.

In contrast, the other options would either compromise security or not significantly enhance it. Evaluating the color of ID badges does not contribute to physical security as the color alone is not a reliable security measure. Sharing access codes undermines security by broadening access unnecessarily, while allowing unrestricted entry without verification poses serious risks of unauthorized access and potential security breaches.
