That sounds right.
The purpose of the badge is to dilute your personal privacy and announce
your identity to those close enough to see. You can't always tell who is
looking at your badge. People who see your badge in more than one place can
infer that you have moved between places. If you don't want people to see
your badge, you can take it off.
In RFID terms, that's what the Faraday cage is for.
The privacy concerns with badges seem very similar to the privacy concerns
of carrying RFID tags.
I do not hear a lot of expressed concern about wearing a badge.
It's more common to have a pocket available than a Faraday cage.
