Elecom has announced a USB mouse with a built-in optical QR reader that has the ability to read both the traditional black and white versions of those barcodes. Along with that Elecom’s new mouse can also read the newer color versions which actually hold less data and are typically only used as pointers to websites.

2D QR barcodes are basically those weird little square graphics that are made up of what appears to be random patterns of smaller squares. Well in reality (hold your breath) those patterns aren’t random and those small squares can actually hold a surprising amount of encoded text.
