That's neat! The Japanese Apple App site doesn't offer that one, and I've never seen anyone using their phones at the register. I know there is such an app for McDonalds here though. I see the kids flashing their phones to the counter staff. Unfortunately, there are quite a few apps that are only available from the US Apple Store. I've run into this before.
