I’ve noticed a recent change in Walmart Scan & Go (Walmart Pay) that really illustrates how far their purchase tracking goes. If you’ve set up Walmart Pay with a credit card, and you later use that same physical card in-store, Walmart now appears to associate those transactions with your account as well.

I’m fairly confident of this because the app has started showing me in-store purchases that were not made using Walmart Pay. It suggests they’re linking transactions at the card-number level, not just through the app.

I suspect they may also be tying in-store purchases to your profile if you’ve ever placed an online order, though that part is speculation.

Yes they 100% associate the card number with your account if it's on file. I have never used Walmart pay and use my physical card only. The strange thing I've noticed is that there is a failure rate of probably 20% where it doesn't associate me.

I do not use the app or scan and go. But I have a walmart account, and if I use my credit card at walmart all of those purchases show up on my online account. My email is of course intimately tied to my credit card (I am not in payments, so I am not sure where that happens, its not surprising but its there).

Menards has done this since at least 2012

That’s really interesting. I always thought grocers probably tied loyalty cards and credit card hashes but it’s interesting that it’s been in home improvement that long.
