The Man Who Invented QR Codes

In 1994, Masahiro Hara got tired of having to scan six or seven barcodes on every box of Toyota car-parts that zoomed past him on the assembly line. He wondered why the standard barcode from the 70s was still used...Why couldn’t someone invent a barcode that used two dimensions instead of one that could work from any angle or distance, even even if it got smudged or torn? And so, studying a game of "Go", he dreamed up what we now know as the QR Code — the square barcode you scan with your phone. It shows up on restaurant menus, billboards, magazine ads — even tattoos and gravestones. But even that, says Hara-san, is only the beginning. Learn more about your ad choices.
