Cash is king in the oases. There is at least one bank with an ATM in every oasis except Farafra, though the ATMs may refuse foreign cards or simply be out of order. Exchange services are nonexistent outside hotels, which may be willing to change your money or accept foreign currency in payment. The best advice is to change money in Cairo and bring plenty of Egyptian pounds with you.
