QR codes that can store data for millennia The world's smallest QR code (Image credit: TU Wien) Despite its record-breaking size, the QR code is even more impressive for its durability, the team said
- Smaller Than Bacteria: The Nanoscale QR Code That Could . . .
A QR code smaller than a single bacterium Etched into silicon carbide Capable of surviving for centuries — possibly millennia — without degrading That’s the claim from researchers at Toyohashi University of Technology in Japan, who have fabricated what they say is the world’s smallest QR code, measuring just 1 77 micrometers on each side For context, a typical E coli bacterium is

Scientists created the world’s smallest QR code using ceramic tech, opening new possibilities for ultra-durable, energy-efficient usage
- World Record: The World’s Smallest QR Code | TU Wien
The QR code covers an area of just 1 98 square micrometers — smaller than most bacteria The record has now been verified and officially entered into the Guinness Book of Records
- Worlds Smallest QR Code Is So Tiny Its Invisible to The . . .
The smallest QR code in the world is so very tiny that your phone would need an electron microscope to scan it The matrix barcode covers just 1 977 square micrometers That's smaller than some bacterial cells or air pollutants The seven scientists who created it were awarded the Guinness World Record on 3 December 2025
