The US dollar is the currency used in Panama. If you come from the United States, you do not need to exchange currency. However, if you arrive from another country, such as the Eurozone, then you will need to exchange currency. Regardless of where you come from, you can withdraw $500 per day from the ATM with a debit card or use credit cards that are widely accepted. To exchange currency, you can go to a Banco National in Panama. There are also several currency exchange desks at Tocumen International Airport.
