The official currency is the Dinar (JOD), which is divided into 10 dirhams, 100 piastres or 1,000 fulus. Foreign currency can be changed at any bank or moneychanger. Banks are closed on Fridays. Better hotels will also exchange money. American Express, Visa, MasterCard and Diners Club are the most widely accepted credit cards and can be used at major hotels, restaurants and tourist shops; cash can be withdrawn from inside banks. ATMs are available, though acceptance of foreign cards is limited.
