In OfficeRnD, members/employees can invite guests and visitors to their workplace. Keep in mind the difference between the two:

A guest is a company member/employee (a teammate) invited by another member/employee to a meeting. The organizer can add guest members when booking a meeting room. The booking invitation automatically gives them access to the meeting room.

A visitor is a person who is not a member/employee. The booking organizers can add visitors by providing their name and e-mail address, where they will receive an invitation.

In the Admin Portal, go to Visitor Hub > Visitor Log. Here, you can see a list of pre-registered and checked-in visitors and filter and export the available visitor data.
