    A QR Code encodes a string of text. In can be a URL, or anything else. Like the DOI string above, a quote, or whatever. You can’t do full Unicode I think, it’s 8859-1, or something like that, although there’s also an Asian variant.

      But your camera phone can already copy text. If it’s a tattoo about the first paper you wrote, whatever you make needs to work for 60+ years. Text is always going to be valid, who knows when QR codes will become obsolete. 60 years ago you’d be getting a tattoo of a punch card, and that would be mostly meaningless today.

        I was just addressing the fact that QR Codes were only for URLs. As for whether they’ll be around in 60 years… Barcodes have proved to be fairly resilient.

        My camera phone can’t copy text :(

        (Original iPhone SE, so not recent, but not ancient or a flip phone or anything)
