The availability to use a card in Cuba remains extremely limited due to the US Trade Embargos and the developing payment landscape in that country. While some areas of the embargo have been lifted, many remain. It is important to note that there is a high likelihood your cards of any brand will not be accepted or function in this area. Furthermore, the Credit Union will not be able to exclude your card to allow these transactions. Any one travelling to Cuba should be prepared with local currency before they go.
