If you go to a bank and ask for one they should know what you are talking about. However it might a U.S. thing, I'm not sure. When I travelled abroad I used traveller's checks and the deutsch mark since I was mostly in Germany. Good luck.

If you're near a 7/11 then they'll have them too, but I never saw a 7/11 in Europe when I was there. I think they are a U.S. thing too.
