liztai, I remember the days when I had to travel abroad often, and often dreading the money changing, and worrying that my cards will not work abroad. So I had to bring far too much cash sometimes. This is kinda cool and I wonder if other regions have this. Would be cool if this system extends to China and South Korea. They are currently working on one with Japan now.
