Yes, The United Nations Federal Credit Union (UNFCU) has started issuing chip cards. Credit Union members are diplomats and their family members stay in-country for extended periods of time, living as the locals do. Members have been asking for an international payment card for years and they'll begin receiving them in late summer/early Fall of 2010. The UNFCU is the only one that's made a public announcement, but that's expected to change. There are other financial institutions looking to provide cards to customers who frequently travel internationally.

As reported in a recent USA Today story, Wal-Mart is changing its payment system to begin accepting chip-and-PIN cards. The retail giant is advocating for enhanced security and the convenience of providing customers with the same payment experience from store to store, anywhere they travel in the world.
