Like most other European nations, Spain and Portugal use the euro (EUR) as their official currency. We recommend bringing your money in the form of debit or credit cards, as they are accepted almost everywhere. However, make sure to have some extra cash (from 50 to 200 euros) in case of an emergency. It's always a good idea to keep different means of payment separately and not to carry all the money with you while going sightseeing or shopping.
The most convenient way to get cash in Spain and Portugal is to withdraw it from ATMs. Although your home and foreign banks can charge fees and set daily limits for ATM cash withdrawals (please check with your bank before you go abroad), itโs still more profitable than to exchange money in banks or currency exchange offices, as they are free to set their own rates and commissions that sometimes can be huge.
ATM stands for automated teller machine
