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.
You can make QR codes that copy text to a clipboard right? Can’t you just make it a DOI search term? Or pay $2/yr for a redirect domain that you can point to where you want later
Might be obsolete after a bit though. A QR code only points to a URL and that might change (unlikely, but after 20 years…)

My camera phone can’t copy text :(
(Original iPhone SE, so not recent, but not ancient or a flip phone or anything)

Where are you getting domains for $2 per year?
.xyz Domains that are just numbers are $1 per year. and netcup has a deal a few times a year that prices .de domains at 1,30€ per year.
