As you probably know, we love our clocks here at Hackaday. Odd display technologies are always interesting to see, as are unusual encoding techniques such as binary, ternary or higher-radix number ...

For the longest time we’ve been using UPC bar codes to store strings of information in a compact space on both product labels and people in dystopian sci-fi movies. But as our needs grew and became ...

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 ...

QR codes, originally developed as two-dimensional matrix barcodes for rapid data acquisition, have undergone significant transformation and expansion in application. Their evolution from simple ...

This year marks the 30th anniversary of the QR Code, the ubiquitous scanning tag developed by a Japanese engineer that is used in every facet of modern commerce. As the technology evolved, the impact ...
