QR codes are mostly meant to let you get an amount of info (they're mostly text-based) without having to type or enter it manually when you might make mistakes or when the process is just faster for the amount of text involved.

Yeah, I know. Why would anyone ever use them if creating one required a certificate? If the certificate was so cheap as to not be an obstacle then it wouldn't be a deterrent to malicious replacement of codes either.
