Reading your post brings a lot of ideas to my mind.

Imagine a game similar to cryptobrewing master adding augmented reality in real places located in different towns. A user could be challenged to have to go to those paces to "pick up" items in order to advance in the game. That would be a way to have people visit retailers in real life and depending on whatever actions they might do, the store could add some points on top of the ones receiving for the actions. Not only retailers could "promote" their places, but also the vendors of those retailers through their products. On top of that, they would also get information of the areas/products where users were engaging.

I have always thought that mixing both worlds, digital and real, is the way to get the best out of a business model. When Pokemon Go was launched it quickly got the attention of many people but since the rewards where only "points" the engagement lasted very short. If you can offer something more as tokens with value in the stores that can make a completely different story.
