I hate the idea of facial recognition tech being used like this but I really don’t mind loyalty cards/using credit cards to track spending as long as the data is only used by the stores themselves (and not also sold wholesale to the highest bidders, which I bet it is).

I think it’s fair for them to gather analytics on spending habits and use it to make decisions on how to stock their store, run promotions, etc. Same for personalized coupons. Feels weird, but is pretty harmless, and I’m pretty sure they’re just trying to get you to try new things (like for me, beyond meat) so you start regularly purchasing it.
