The currency varies in each country around Asia. In the articles linked above, you'll find reference to the Thai Baht, the Indonesian Rupiah, the Vietnamese Dong and the Malaysian Ringgit. Unlike most countries, one of the easiest ways to obtain local currency is by bringing U.S. dollars (or your home currency) to exchange. In many places, this turns out to be a huge scam, but I've found it to be fairly reliable in Southeast Asia. The easiest and safest way to get cash in Asia is by taking it out of a reputable ATM. Follow some basic practices when taking cash out in a foreign country: –Make sure your bank knows you'll be traveling (and where) so your card isn't declined –Hide your PIN number when you type it in –Only use ATM machines attached to a bank or another reputable establishment
