This is not a SFW instance. NSFW communities will be tagged, and efforts will be made to keep SFW communities clean, but proceed at your own comfort level.
Leave all the normal headstone stuff on the headstone. Also add a QR code, like these mortuaries are doing. But instead of making it just a URL to some sort of memorial page for the deceased, encode their obituary into the plaintext of the QR directly, and add a URL to the memorial page at the end of that text for people who want to see photos or sign a digital guestbook or whatever. That means that, even if the mortuary goes out of business and the URL no longer leads anywhere, the obituary is still readable by anyone with a smartphone.
I don’t think anyone is suggesting just a QR code.
What’s then the point @LodeMike@lemmy.today is trying to make?

That’s my guess.
