I can't imagine a qr code on a receipt being anything but tracker-infested spam.

  That's how it currently is in some shops. Amazing how marketers are always ahead on such technologies.

  Can confirm. I was visiting a nature reserve where the trail opened to a resting area with some seats. A tree had a woodcut QR code on it, so I thought I'd scan it to find out more about the area. Turns out, the QR code linked to some tracking site with a short URL. Even worse, the short URL had since been deleted, so I have no way to know the original URL it went to.

  Yep, it'll definitely have a tracking code added to the URL.
