Patrons of the vending machine can use the cameras on their smartphone to snap a photo of the QR code, allowing themselves to check in and assigning themselves an avatar. Over time you will be able to customize that avatar by accessorizing it with shoes and hats while the machine chats away to you about the weather, and it even remembers your birthdays too.
Badges and various achievements can be unlocked as well, allowing you to compete with your friends and strangers over how many badges you might have earned. A rather interesting and novel concept, although we’re not sure if that concept will take off in any other part of the world.
