The official currency is the Kyat (MMK) pronounced 'Chat'. The best foreign currency to travel on in Myanmar is the US Dollar. The Foreign Exchange Certificate (FEC) is a legal currency for visiting tourists that is usable in government shops and hotels. US Dollar notes will not be accepted if they are damaged or torn in any way, or have pen marks on them. There is a big difference between the official and unofficial exchange rates in Myanmar; street moneychangers offer favourable rates at hotels and markets. Few major hotels, airlines, shops, and restaurants accept credit cards and ATM cards can rarely, if ever, be used. It is advisable to carry cash.
