Reverse image search can be based on an image URL. So theoretically ...
But I'm failing to create such a link right now, because everytime I'm reverse searching the same QR code image URL, something different happens. Sometimes I land on a web version of lens, which sometimes only shows QR-Code content and sometimes makes an additional similarity search, and sometimes I land on classic image search, which sometimes finds nothing and sometimes finds other QR codes. 🤪

But that was not your question.* 🙈 Now I get it. Yeah, that's an interesting question. Self containing QR code. 🤔
