On my first solo trip to Bali, I took 2 bottles of wine. I was hit up for a bribe by the customs agent. He wanted US$10. Considering the high price of wine in Indonesia, it was probably not such a bad deal. Unfortunately I didn't have any US currency.
Other forbidden items: firearms, narcotics drugs, pornography, Chinese printed mattr, Chinese medicine, transceivers, and cordless telephones.

The Indonesia Rupiah is also called IDR. Information of daily exchange rate can be found in newspapers or from the net. Some Indonesia banks provide this on their websites. IDR and US$ are the most acceptable currencies. Most resort hotels can change money for you.

Credit cards are accepted only at major hotels, restaurants, shops, and travel agencies. It is also advisable to keep a good supply of small bills as many taxi drivers and small shopkeepers might not be able to make change.
