Scenario 1: You’re walking around in a town you’ve never been to before, collecting menus from restaurants that you’re hoping to find some decent local food from. But instead of simply handing out takeaway menus, you notice many of the restaurants are providing an eco-friendly QR code for you to scan to see their menu and effectively have it with you at all times on your phone.
Scenario 2: You’re out at a concert, listening to one of your favorite bands, when all of a sudden, you notice the guitarist is wearing a shirt with a giant QR code on the back of it. Being in the 7th row and knowing what a QR code is, you take out your phone so you can get a picture of it to see what he wants you to see. Lo and behold, you’ve just earned a secret backstage pass right there on the spot that no one else can win now because you were the first to access it!
Scenario 3: You’re flying over a city about 15 minutes out from landing at your destination, when all of a sudden, you notice an incredibly massive QR code that has been painted on the top of an entire building. Once again, you take out your phone and quickly take a picture so you can see what it’s all about (be it a URL, phone number, text message, or otherwise) once you’ve got cell service again.
Those barcode-looking things? They’re called QR codes. Here’s what they do. ZDNet
