They don't ask for anything except money. You can buy a 7 day visa for 10 US Dollar or a 30 day visa for 25 US Dollar. These are tourist visa, for any other type you have to go to the Indonesian Embassy at Tobias Asserlaan 8 in Den Haag (The Hague). They are actually quite helpful there.

You can't get visa on arrival (VOA) at all indonesian airports and seaports, but the ones most often used offer it (Jakarta, Surabaya, Denpasar, Medan, Menado). They payment methods differ per airport.

In Jakarta, you can pay with Visa or Mastercard, but even at Surabaya that was not possible. They did accept a combination of Indonesian Rupiah and Malaysian Ringgit. Dollars and Euro are also possible.

If you want to be on the safe side, bring US Dollars. Best options and best exchange rate. A couple of times I even went through immigrations, found and ATM, went back and paid the Visa in Rupiah. Just ask one of the officers.
