Automatic teller machines (local name: Bankomat) are very common in Croatia. You can find them in both large & small cities, tourist areas etc.
You do not need a chip & PIN card to use an ATM — your standard magnetic 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.
ATMs category is available in production API version 2.
