Coca-Cola Japan is giving away free bottles of two new teas with a QR Code promotion. Coca-Cola Japan sells lots of bottled tea, also lots of cans of coffee! If you see the advertisement (example picture below) you snap the QR Code with your mobile device and when you want the free tea hold up your device to a vending machine that accepts payment via mobile. The vending machine will recognize the coupon and give you your free tea. (You can pay a vending machine with your cell phone in Japan and vending machines do have cameras!). Hat tip to Nagoyankee on Japan Forum.
