World's smallest QR code, smaller than bacteria, could store data for centuries

A record-breaking microscopic QR code could make data storage last for centuries-no electricity required.

Summary:
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.

How small can a QR code get? A team of researchers has pushed the limits to an extreme, creating one so tiny it can only be detected using an electron microscope. Scientists at TU Wien, working with data storage company Cerabyte, produced a QR code measuring just 1.98 square micrometers, which is smaller than most bacteria. This achievement has now been officially confirmed and recorded in the Guinness Book of Records.
