Automatic teller machines are everywhere in Portugal. Pretty much anywhere you look there will be an ATM. Portugal has one of the highest ATM densities in the world.
You do not need a chip & PIN card to use an ATM — your standard magnetic or chip & signature card will work fine.
The exchange rate you'll get on an ATM is usually the best one you'll get. You’ll pay fees, but you’ll still get a better rate than you would exchanging cash at a bank or exchange booth.
Usually you can only withdraw money from your checking account. You will not be able to withdraw money from savings account or transfer funds between accounts.
ATMs category is available in production API version 2.
