Riel (KHR) is the official currency and is divided into 100 sen. Foreign currency can be difficult to exchange, with the exception of US Dollars. Most transactions require cash but credit card use is on the rise, especially in tourist-orientated hotels and restaurants in larger cities and towns. US Dollars and Thai Baht are accepted, although smaller transactions are usually done in Riel. A torn US Dollar note is useless. There are ATMs in Phnom Penh, Siem Reap, and Sihanoukville but they shouldn't be relied upon as a source of money.
