The official currency in Flores is the Indonesian Rupiah (IDR), and cash is primarily used for transactions. International money transfers are not commonly available, so it’s a good idea to bring cash with you. While ATMs that accept Visa and Mastercard can be found in major towns, ATM access can be limited in smaller towns and rural areas, so plan ahead. Banks can exchange foreign currencies into rupiah, and you’ll also find local money changers in Labuan Bajo. Always check the exchange rates and fees before making any transactions. Note that traveler’s cheques are rarely accepted, so it’s best to rely on cash or card payments.
