World’s smallest QR code created in major data breakthrough

• 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, was engraved onto a special ceramic using beams of charged particles.
• Officially recognised by Guinness World Records, the code is so small it can only be viewed under an electron microscope.
• This ceramic-based storage offers exceptional durability, retaining information for hundreds of years without requiring power or maintenance, unlike current digital storage methods.
• Researchers aim to scale up the technology for industrial applications, potentially allowing over two terabytes of data to be stored on an A4-sized area.
