What currency do I need, and are there ATMs?
Indonesian Rupiah is the currency, QRIS is widely accepted, and ATMs already exist, though not necessarily right on the tourist route.
Indonesian Rupiah is what you'll need, it's the only currency accepted. QRIS is well established with local vendors if you have an Indonesian bank account or e-wallet, and ATMs from state banks already exist in IKN, though not necessarily near the main visitor plazas. Full bank branches with counter service are still being built. Bringing cash from Balikpapan remains the sensible backup either way. Full details are in our Travel Guide.
