Cambodia - money - Countries Guide

Riel (KHR) is the official currency and is divided into 100 sen. Foreign currency is difficult to exchange with the exception of US Dollars. Most transactions require cash. US dollars and Thai Baht are accepted, although smaller transactions are usually done in riel. A torn US dollar note renders it useless. Credit cards are only accepted in a limited number of tourist-orientated hotels and restaurants in Phnom Penh and larger towns. There are a few ATMs in Phnom Penh, but they shouldn't be relied upon as a source of money; travellers cheques in US dollars or sterling can be cashed at a limited number of banks and larger hotels, though travellers cheques are not recommended due to limited acceptance.
