QR codes require the background colour (white) to extend at least 5 pixels around the corners. This won't scan.

Fun story time. My wife Rick rolled me during our wedding ceremony. She asked to officiant if we could each send him a secret passage to be read during the ceremony. The officiant read my passage, the Dr Seuss passage about finding someone with compatible weirdness, then he started her passage "you know the rules, and" and at the moment I knew I'd been had. It was awesome. He went all the way through the first chorus.
I made stickers with the qr code. Now half my city has random qr codes hanging around.
