There are two ATM machines in Antarctica. They are located at McMurdo Station and operated by Wells Fargo. Here’s an interview with a Wells Fargo VP about the unique challenges of operating those machines.

You know, the other thing too that you may find interesting — I don’t know how much you know about folks that need to go down to Antarctica — it’s a huge process to do it. So when we’re preparing for the vendor visit, it’s like a ten-month process. The reason being is, they obviously go in the off-season when it’s obviously warmer because no planes fly onto the ice in their winter months. And so anybody that goes to Antarctica has to be cleared with a physical, a dental, and a psychological evaluation, because if for some reason the plane can’t get out, you’re trapped down there until the next season.
