QR Codes are a 2 dimensional barcode used to store information to be scanned by your mobile phone device. They are included on every blog post as a black & white square at the beginning of each post to direct you to the article using a mobile phone. If you do not have a barcode reader on your mobile, download one for free. Red Lazer for the iPhone is a good free barcode reader, but there are lots of different barcode readers to choose from.
