You can use QR codes to get in game loot in Borderlands 2, with the LootTheWorld App all QR codes you scan can turn into awesome guns!
Article from GameInformer:
2K Games and Gearbox have released a new app that puts Borderlands 2 loot in the palm of your hands. With the LootTheWorld app, you’ll be able to scan QR codes and turn them into unlockable in-game loot.
Here’s how it works. First, download the free app from the App Store or the Google Play Store. Then, login with your Shift account. Finally, press the “Shoot” button to scan a QR code.
You’ll start with three stamps, each of which can be traded for one item to be sent to your in-game character. More stamps can be earned with some QR codes (keep an eye on @GearboxSoftware on Twitter). You can store 20 items for later unlocking (in case something is a bit overleveled for you), and you can delete ones you don’t want individually.
Each user also gets their own QR code to share with friends so if you try it out post them here so everyone can get awesome stuff!!
