MONEY in BALI
Currency: Currency in Indonesia is the Rupiah, IDR. Rp is the official abbreviation. Rp 20,000 for example.
Note: The exchange rate to the U.S. dollar as of 2010 is approximately Rp10,000 to $1. Indonesia, like Korea, uses large denominations but your money stretches a lot farther in Indonesia. The withdrawal limit from ATMs runs from Rp1,000,000 to Rp3,000,000.
Tip, Caution
For the most part, I could only withdraw Rp1,000,000 at a time, which is only $100 USD. I withdrew twice or three times so I didn't have keep hitting up the ATM machines. However, remember that you pay 1. an international transaction fee, which is a small percentage of the amount you withdraw 2. a non-bank fee.
(I don't know why most ATMs in Bali (and Ubud) restrict you to Rp1,000,000 limit. I can only speculate that the banks want to collect fees from Bali's heavy tourist traffic. Or, perhaps people tend to overdraw and exceed their withdraw limits.)
Accessibility
Kuta: There are ATMs everywhere in Kuta, Legian and Sanur and Nusa Dua. In Kuta, I could not find a truly wheelchair accessible ATM in Kuta. You have to go to the Discovery Shopping Mall.
Sanur: There are wheelchair accessible ATMs along Jalan Tamblingran. You will find a BNI (Bank Niaga Indonesia) and a Commonwealth Bank ATM (I believe Commonwealth) across from each other in a nicely recessed entrance and parking area in front of Penjor Restaurant.
Banks & ATMs: The major banks and ATMs you'll see in Bali -
BNI (Bank Niaga Indonesia) is actually CIMB group and will show up as Bank CIMB Niaga, Indonesia (mergers) on your transaction receipts.
I used BNI (in Sanur), BCA (in Kuta) and Bank Danamon (Ubud) during my trip.
Withdraw Limits
Money Changers
Remember that Bali is a tourist trap and that the Balinese are trying to make money at every turn. That being said, the expats in Bali mentioned that Circle K money changers are the fairest, legitimate. The streets are full of money changers (Jalan Legian, just north - maybe 100 yards - of White Rose Hotel and the Memorial) but, as usual, you'll get terrible rates and often no official receipt.
Just be careful. As usual, I prefer ATMs over money changers, espcially in Bali, even if you're docked international transaction fees and a couple of dollars in non-bank ATM fees.
Sales Tax
Generally speaking, only restaurants and hotels charge sales tax - from 10 percent to 25 percent, depending on the class of the establishment. For everything else, you don't get taxed. That goes for convenience stores (though I heard that alcohol and cigarettes are taxed) if you buy water, etc.
Tipping: No need to tip
