Indonesia's official currency is rupiah, which is broken down into 100 sen. You can exchange money, especially US dollars, at hotels, banks and exchange bureaus. Traveller’s cheques aren’t always accepted, and cash usually gets a better exchange rate. Hotels, restaurants and stores that cater to tourists usually accept major credit cards. Main city centres have ATMs. It’s a good idea to hang on to small change and notes for small purchases like bus fares, drinks and temple donations.
