World's smallest QR code can store data for thousands of years — but you need an electron microscope to see it
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 ...
Researchers at TU Wien in Vienna have created a QR code so small it can only be read with an electron microscope. The code measures roughly 1.98 square micrometers, with individual pixels about 49 ...
