QR codes ? What the hell are they ? A QR code is like a barcode but can hold loads more information. With a simple application installed on their phone, users can take a photo and watch the code convert to real text or direct them to other content. OK, so the practicality is what? Well, quite a few things actually. Imagine, you're given a business card with a QR code on it. Snap it and all the donor's details are instantly inputted into your phone. No mess, no fuss. McDonald's have QR codes on all their food wrappers so that patrons can photo and then view the nutritional info on the phone(yeah right!). Loads more innovative uses are springing up all the time... how long til it reaches the UK (given that there are already English versions out on the web)?
