Actually, when I read the original post, I was wondering what the QR code was supposed to be useful for. Your thoughts make sense. The scammer may put a URL in your QR code that points to a redirect URL that pretends to forward people to OP's Amazon page when users are actually sent somewhere else, e. g. to a phishing site that siphons off Amazon credentials and credit card data.
