Easy enough to associate your Magicband and your rose-shaped beeper...which very likely has a GPS chip in it...
Those roses appear to also be RFID from descriptions. The tables themselves may have receivers.
GPS would not be useful at the granularity of tables in a restaurant - it's not that accurate. But there are some indoor radio systems, and it could use one of those.
