Do stores use bank account info to analyze shopping patterns? (mander.xyz)

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?

How does that work for broadcasts from your device, designed to prompt beacons from dorman aps you might have joined before? Once you join it provides a random mac, but before then?

They use randomized MACs there too.

You can set MACs to not randomize for specific WiFi, but by default it's on and random.
