Out of a reflex of distrust, I refuse to participate in any kind of loyalty program of the outlet of the large retail store around the corner.
I tell myself that by refusing to join the loyalty program (which basically comes down to scanning an anonymous loyalty card every time I make a purchase), I prevent them from adding my correlations (what products I buy, in what combos, at what time) to their data.
But since I normally pay by card, I guess they can (and do) already do that with my bank account information?
If I would pay with cash, they can still see those correlations per purchase, but they can’t track my purchases over time?
Yes, a good bit of stores do. I pay in cash generally, and I don’t tie my email to my bank account. The nice thing with paying cash is you have a better idea of how much money your spending too.
But as some other users mentioned, some stores have these camera’s in the parking lot that track your license plate. Generally park in a way that it cant see it when you enter or leave.
