Even though they don’t seem to be as popular in North America as they are elsewhere odds are you’ve seen those 2D QR barcodes at some point. You know, they’re those weird little square graphics that are made up of what appears to be random patterns of smaller squares. Well in reality those patterns aren’t random and those small squares can actually hold a surprising amount of encoded text.
Elecom now has a USB mouse with a built-in optical QR reader that can handle both the traditional black and white versions of those barcodes as well as the newer color versions which actually hold less data and are typically only used as pointers to websites.
