Just how small can a QR code be? Small enough that it can only be recognized with an electron microscope. A research team at TU Wien, working together with the data storage technology company Cerabyte ...

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 ...

Scientists have created the smallest QR code in the world, measuring just 3.07 × 10⁻⁹ square inches (1.98 square micrometers). It can preserve data for thousands of years and it's so small that you ...

For those of us who weren't paying attention, over the last few years, scientists around the world have been one-upping each other in a bid to create the smallest QR code that can be reliably read.

Tiny details: QR codes are designed to efficiently and securely store digital data in a compact, two-dimensional form. Researchers at TU Wien took this principle further – delving into the microscopic ...
