The official currency is the Turkish Lira (TRY), which is divided into 100 kurus. Currency can be exchanged at banks, exchange booths, post offices, airports, and ferry ports. Note that banks have the worst rates but will exchange lesser known foreign currencies. Banks open mainly Monday to Friday, but some are open daily in tourist areas.ATMs are widely available in major cities and tourist areas, but Turkish ATM keypads usually do not have letters of the English alphabet on their keys. Major credit cards are widely accepted; the most popular are Visa or MasterCard, but American Express is also accepted in some areas. Some hotels in the most popular destinations accept US dollars as payment.
