Scientists have created a microscopic QR code so tiny it can only be seen with an electron microscope—smaller than most bacteria and now officially a world record. But this isn’t just about size; it’s about durability. By engraving data into ultra-stable ceramic materials, the team has opened the door to storing information that could last for centuries or even millennia without needing power or maintenance.
Actually QR codes can have something like 99% error correction as long as you’re storing only 1 byte and use the biggest QR code format. It’s common to scale up by 1 format if you want a logo in the middle.

Most encoders are just programmed for 30%.
