The unit of currency is the Egyptian Pound (EGP), which is divided into 100 piastres. Most credit cards are accepted in major hotels and restaurants. Banks are usually closed on Friday and Saturday, but private exchange bureaux, called 'Forex', are open daily and banks in major hotels are open 24 hours. Cairo branches of the Egyptian British Bank and Banque Misr have ATMs available that accept Visa, MasterCard and Cirrus and are quite common in the main tourist areas.
