Would you still call a ribbon-hung badge a badge if it were to be worn to show you have permission to leave a place, enter one or use a facility? Would the place make any difference if it was a factory, company/organization or school?
I think a badge is generic enough to use it in various situations, other than as an ID or to show you are a visitor, and whether hung around the neck, pinned or sewn to clothes.
Someone suggested I call it a pass or a permit. What do you think?
