Is there a fee if I use my debit or credit card overseas?

If you use your Visa debit or credit card while you are traveling internationally or make a purchase with a company that bills from outside the US, Visa will add a 1% surcharge to each transaction with the exception of the Signature credit card. The fee will appear as a separate item on your statement.
This is Visa's currency conversion fee. The credit union does not add any additional charges to your international transactions.
