I did a little research on this, and it has many applications outside OHS. It uses global positioning systems (GPS), RFID, Wi-Fi, or cellular data to set boundaries. Kinda like the fenceless dog boundaries without the collar, though maybe it could be used in the prison systems, like in the movie Running Man

. Marketing, timekeeping, fleet tracking (waste shipping applications), security, and worker safety. I don't see how it could be used inside a facility.
