Cash basis payment is the general way of payment in Flores and only Rupiah (IDR) is accepted for cash payment. Money transfers are not usually possible, as using International account is not very common yet. There are ATM in the district capital depending on the Bank-accept major credit cards (Visa and Master Card) where you can get cash. The ATMs of BNI (National Bank of Indonesia) are the most reliable. The Bank can also change your foreign currency into Rupiah. Travel Cheques are rather difficult to change.
