At very least they know what the merchant sells.
Yes, that's one way they limit the use of some cards (you could have a debit card that is only allowed to be used for gasoline purchases)

Here's an interesting one for you if you have a Walmart online account. If you use the card to make a purchase at any point using the website logged into your account it'll recognize that card with your account when buying in person in store. You can log into your account right after buying and see every item you bought in that in store transaction.
I didn't know they had ones that limit purchases, but I know they have different perk or cash back levels based on the items purchased or for certain stores.Yes, that's one way they limit the use of some cards (you could have a debit card that is only allowed to be used for gasoline purchases)
Interesting. Mine always do.Nope. I don't see that. I used my card to purchase a 256GB sd card online from Walmart for curbside pickup.
I later purchased some usb thumb drives in-store from that same Walmart.
Guess which purchase does NOT shop up when I look my purchases on Walmart.com?
That's right, the in-store purchases.

As far as bank and retailer, that's probably not how they're getting the email address. It's out there somewhere tied to your information and advertising companies find it financially beneficial to connect the dots.
I haven't used walmart online, but some do. I shop at REI online and in store and my in-store purchases will show up. I don't know how common this is with other stores though; Kohls.com doesn't do it. But, I'm also an REI co-op rewards member so I don't know if the same applies to non-members since my purchases will be tracked via my member number.Nope. I don't see that.

That's a mistaken assumption.What does my access point have to do with this? Nobody but me knows the MAC address and private IP address of any device connecting to my router via my access point.
That's a mistaken assumption.
The signature must be left somewhere in the handshake that happens with websites and pages we visit because that's how things are encrypted. The whole hacker thing that you don't want used for theories have to have certain signatures they can pick up to get enough to access devices. Call that tinfoil if you want but that just happened a few days ago with my oldest child. I happened to be around at the time to witness this person accessing her webcam trying to extort her for money. Unfortunately because I don't know what they used and how they got into her computer, the only thing I could do was wipe it and reinstall the OS and start from scratch.Really? Explain that one. Omit any theories about hackers. Or routers preloaded with spyware. Or whatever the tinfoil hat conspiracy of the day is.

That's what some restaurants do.Your access point tied to your address and your card tied to your address. If you have wifi enabled on your cell phone then your access point tied to your GPS location tied to your address. If you have made a purchase online then Google and/or Apple will know the card number as well.
It's quite fascinating how data points can connect. You can be pinpointed and identified based on deidentified data points.
That's what some restaurants do.
Fred Meyer/Kroger does this, and knows exactly what is bought because of someone's rewards card. They send me coupons where about 80% of them are for products I typically buy, and it saves a lot of money due to the coupon discounts - which I like. I don't think they share my info with anyone else, because seems I only get stuff related to groceries from Fred Meyer/Kroger.Grocery stores need to keep track of what is sold to keep store stocked.
They still do that, but now keep track of what you bought to advertise to you.
You have a rewards card or similar with them?Ok, but the retailer doesn't know what my email address is (unless I gave it to them). My bank should NOT be giving my email address to a retailer.
@brianl703 I think we are talking about two different things. Websites are a very minor issue here. You should focus more on what Google and Apple know about you through Android or IOS. That little device in your pocket is what tells them everything about you. Even if you disable location services, Wi-Fi, etc. the OS will still communicate these data back home because privacy restrictions only apply to the third parties.

I think a lot of people who can't connect the technology dots must think it is a conspiracy, lol.Really? Explain that one. Omit any theories about hackers. Or routers preloaded with spyware. Or whatever the tinfoil hat conspiracy of the day is.
