Asking people who use #screenReaders: what is the best way to add #AltText to a QR-Code? Are the screen readers clever enough to recognise it as such and offer to read the contents or follow the link? Does putting the content of the QR-Code in the alt text help? or would it make it worse, especially if it is an URL?

boosts are welcome

(the whole point of the post that prompted this question was posting a QR-Code, so no, I couldn't have just posted the URL)
