I had USAA set me up with a low limit VISA card that I use as my travel card overseas (for me mostly to Latin/South America and Caribbean).
Yeah that's smart. I was surprised when I was in the Middle East how often my Discover was accepted; and only recently (I think) NFCU did away with foreign transaction fees for their Cash Rewards card as well, which is definitely something to keep in mind if you're going to be buying a lot of stuff in foreign currencies.
