in this post. The problem with all of those posts is that they rely on the use of some type of phone camera or webcam. Thanks to a Tweet by Doug Peterson this morning I discovered a solution to that problem.
QRreader (beta) is a Google Chrome extension that allows you to use your browser to decode QR codes. With QRreader installed when you come to a QR code on the web you can simply right-click on it to decode it. If the QR code is for a webpage, the page will open in a new tab. If the QR code is for text, it will open in a text dialogue box.
On a slightly related note, Chrome recently overtook Internet Explorer as the most-used browser in the world. The wealth of handy extensions like QRreader is one of the reason that I and many others prefer Chrome over all other browsers.
