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 ...

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 ...

Adding a camera to a project used to be a chore, but modern camera modules make it simple. But what if you want to read QR codes? [James Bowman] noticed a $7 module that claims to read QR codes so he ...

Sometimes, we try to capture a QR code with a good digital camera on a smartphone, but the reading eventually fails. This usually happens when the QR code itself is of poor image quality, or if it has ...

The Institute of Materials Science and Technology at TU Wien now has its own entry in the Guinness Book of Records for the smallest QR code.

With a little casual hexadecimal memorization and pattern recognition skill, you can become a QR code-reading machine — no pesky computer required! The black and white boxes represent binary 1s and 0s ...

A study by the University of Barcelona and the Universitat Oberta de Catalunya presents a mathematical solution to make it easier to read these two-dimensional codes on deformed surfaces, such as ...
