"This year at ISTE in Atlanta, I shared with teachers one easy way to add QR codes to three-dimensional shapes.   The app Foldify lets users create a template for a variety of three-dimensional shapes.  Instead of drawing a picture or adding family photos, I used a QR code generator on my iPad, saved the pictures to the Camera Roll, and placed them on my Folidify creation.  They are easy to assemble after your print them out and great for having students roll a dice for a mystery writing prompt or math problem."

QR codes are beginning to gain ground in the UK so I've decided to write an article covering the brief history of barcodes and the lead up to the introduction of QR Codes to give you an understanding of the technology. I've been in IT for 20 years and, as with most technically orientated people, I tend to fall into the 'techie' trap when writing articles explaining technology. The article normally ends up reading like a technical manual for NASA's space shuttle so I've made a conscious effort to stick to layman's terms to make the article clear for a wide audience.
