Protip: Many grocery stores allow you to just grab cards without signing up (in the US at least). You can tell them you'll send it in later.

Then, you can use whatever the fuck info you want and still get the "rewards" so it's not attached to you. If you use the apps on your phone, make sure they don't have bluetooth access.

Pseudonymous data isn't anonymous. And they can probably just match it to your CC info anyway.

[-] geosoco@kbin.social 2 points 1 year ago

Yes-- same with bluetooth or ordering groceries for delivery and giving your home address. There's always ways to leak data and make it no longer anonymous. However, from my knowledge of how some of these datasets work, they aren't putting in a lot of effort into truly trying to make sure the joins are 100% accurate because it rarely matters. They generally don't give a shit about you as an individual. The most common uses of the data are for advertising and mistargeting doesn't cost enough to justify the time to verify the data.

Paying in cash though can make it anonymous, or by using virtual cards that mask your card id.

Unfortunately, my experience is you have to register them first. I too have a worthless piece of unregistered plastic like that (Kaufland Card).

Sure, but you can usually register with fake info though. I've never seen one really verify much of any information.

Just use one of those email forwarding services that generates unique addresses.

everyone can sign up as "JP Morgan" at "555 Fuckoff Lane". I'm guessing it might be better if we all standardize to make it harder to connect the sold datasets. If they have address checking we should find some tiny town with 200 people from google maps.

Why not to have Bluetooth access?

Interesting, I had no idea this was a thing!

But thinking about it, kinda makes sense for the shops to install them. For their benefit...not ours

Theres always the 867-5309 trick.

[-] SeedyOne@lemmy.ca 1 points 1 year ago

Used it last week on a trip to the PNW, still works. I didn't know the area code locally but asked the checkout guy, popped in Jenny's number as the rest and boom.

[-] ScoobyDoo27@lemm.ee 3 points 1 year ago

That number probably exists with every area code so you could just use your local one if you don’t know.

[-] SeedyOne@lemmy.ca 1 points 1 year ago

Exactly what I did!

When the cashier asks me if I have a card, I usually ask them if they have a card. I get a discount and they get points. Win-win.
