Usually the badge-in spots were grouped at entryways? So, not one attendant per badge reader, but not uncommon to have a choke point that had one. If only for security reasons. Even without an attendant, there would be a camera. And this would present an obvious cluster of badge ins that can be easily inspected.
I think it depends on the company too and how much $$$ they have to spend on such things, but generally there’s an attendant at the entrance badge in points. They not just monitor the entry for people hopping the turnstile, but also greet guests and provide guest badges.
