We’re starting to see QR codes getting used more and more often these days. Heck, I was just at Denny’s this morning, and I saw them on my placemat. If you have a smartphone, you can easily use an app to decode it, and see whatever it is the company is trying to get you to look at. However, what do you do if you don’t have a smarphone?
If you have a way to get a picture of the QR code (or any other barcode, for that matter) to your computer, you can use ZXing (Zebra Crossing) to translate it for you. Just upload the picture to the ZXing site, or link to an image online, and it will give you the output. Pretty simple, right?
