The official currency is the New Turkish Lira (TRY), which was introduced on 1 January 2005, whereby six zeros were dropped from the TL and the sub-unit New Kurush was created. Currency can be exchanged at banks, exchange booths, post offices, airports and ferry ports; banks have the worst rates and highest commissions, 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 alphabet on their keys. Most bank branches have ATMs which accept Cirrus and Plus. Major credit cards are widely accepted; the most popular are Visa or MasterCard, but American Express is accepted in many of the more expensive places.

Travellers cheques can be exchanged at some banks and currency exchange offices, but are not as welcome as cash or credit cards. US dollars or Euros are preferred. Some pensions and hotels in the most popular destinations accept US dollars as payment.
