I'd guess this is done primarily using those "loyalty cards". I
don't know what credit card privacy laws are like in the USA,
presumably not weak enough to allow banks to share buying
information directly with marketers?
Oh, I just read the page you're linking to; it does sound more like
the wifi thing that was mentioned ("at other locations near the
retailer"), but I didn't realise that was already widely deployed.
It's probably a combination of several horrible technologies.
