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.
The smaller the more easily damaged, right? The uffington horse approach will last longer than the website it points to.
Mount Rushmore but with a QR code linking to a defunkt ad page.
