Reminds me of some ~10 years ago I found a dirt cheap game in a budget bin in some store. It contained a few plastic, pre-painted, miniatures, that had some kind of special base with bumps on (possibly in some unique pattern for each miniature?) and then you were supposed to install an app game on a tablet and place the miniatures on the tablet to move them and have their locations (badly) tracked. Seems like it may have been a similar technology, but you only had to pay for the playing tokens and use a standard tablet. Not sure if special hardware is needed for better tracking of enough tokens or if a standard tablet today could be used with the right software?

Game(s) that you were supposed to play was not very fun, in addition to the tracking not working well, as I remember it, but I may still have the miniatures somewhere. There was another game from the same company that I also bought at the same time, but that one was made to be played with a phone camera as some kind of AR game instead, moving some plastic objects on a table, that also worked about as well as the other game.
