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 ...

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 ...

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.

Scientists at Vienna University of Technology have created a QR code smaller than most bacteria, capable of storing data for centuries. The minuscule QR code, measuring just 1.98 square micrometres, ...
