Check out HR codes, an alternative to QR codes which encode all valid URL characters to images. https://github.com/hantuzun/hr-code Human Response Codes are designed to be recognized by humans and OCR.

Great idea, thanks for sharing this! But how could we prove what's behind the image is exactly what is shown? Could someone still hack it, pretend to be a normal link but actually is a phishing link?

How can you know the URL doesn't redirect to something malicious?

The big downside of this is lack of redundancy. QR codes are incredibly redundant. check out images 6 ("lose an edge") and 10 ("blob of paint") in the page: http://datagenetics.com/blog/november12013/index.html

Both of these scan perfectly fine with QR. And in HR, those (and most of other damaged examples) would be unreadable.
