Yeah, that would be much more plausible. As dystopian as Walmart is, I don't think they have phone sensors that can determine your device by just being in the store...

This is definitely how they do it, as someone who has a Walmart account and usually buys through the app. If I buy something in store with one of my linked cards, it stores the receipt in my account (and then asks me to review it)

Pretty sure they could get your MAC address pretty easily if you have Wifi turned on.
