QR Codes, or Quick Response Codes, are all the rage nowadays. You know, those black-and-white barcode-looking thingies that show up on magazines, posters, and even some t-shirts.
A QR Code is actually fairly similar to a barcode: it’s an image that encodes data like URLs, phone numbers, words, and more. You can even take a picture and sort of turn it into a QR code (the picture is uploaded to the internet and the QR code encodes the URL of the picture.) Sure you lose some aesthetic value, but hey.
If your phone’s battery keeps dying on you because you spend all your time playing the wildly popular mobile game Angry Birds (or if you’re too cheap to buy Angry Birds), you should be pretty excited about this latest development.
