Laser etching QR codes onto thin sheets of non-corroding metal or ceramics may be a lot easier to preserve and read back. Also etching the ISO/IEC 18004 standard as text/ images may be doable also. Reimplementing the needed software can be done with today's AI in a matter of a day or two. (I have actually done that over a longer period of time though.)
