This is driving us nuts. There was some movie/series that featured ring-shaped storage/authentication devices. These were worn and we have this vague notion that the characters were trying to swipe/swap them. Can't remember what this was and any help would be appreciated.
@nickchuckwalter Nope. There was something like a data terminal with an interface like a ring holder that connected to the rings.
