    I saw a Youtube video a while ago on how supermarket chains create customer profiles for each credit card. That way, they can get a better understanding of purchasing habits and how consumers react to price changes. Makes finding the most profitable price easy, you see.

    • In the US. In the EU that is illegal. That is why they offer voluntary bonus programs, where the data collection is explicitly allowed by the customer. Unlike facebook it is not necessary for the servicevthough and also they dont sell the data to third parties.

      That’s the case here in Canada, and on top of that it was revealed a year ago that many stores were secretly sending in-person/brick-and-mortar purchase data directly to Facebook/Meta without notifying anyone. Because they get a kickback or something, iirc. (I have to check again but I’m pretty sure that even applies if you have no FB account.)
