The automated teller machines (ATMs) use Latin as a language option in Vatican City, the independent city-state that is ruled by the Pope, or the head of the Catholic Church. The classical language is otherwise extinct throughout the rest of the world, but remains in use in many official capacities of the Catholic Church, including the Vatican Bank.
The Vatican Bank, technically known as the Institute for the Works of Religion, is a private financial institution that was founded in 1942 to handle money used for charity and other religious functions in Vatican City.

Actually, Latin is wildly popular in Finland. The BBC has an article about it, and naturally there's one on Wikipedia.
