In Paxos, the currency used across the island is Euros. If you are going to be visiting from a foreign country where the Euro is not used, you will want to change your cash into Euros before you get here. In case, you have a limited amount of Euros on hand, do not worry because all major credit cards are accepted. This means you can use your Visa or MasterCard here with ease. Since the cards are accepted widely, you will have no problem buying all the essential items you need for the duration of your stay in Paxos.
