What are Iran’s currency, exchange and credit card rules?
Iran’s currency is Rial. In daily trade, Iranians use an older unit, called Tooman that is for 10 Rials. It is possible to exchange money already at the airport, no matter at what time; but only special banks do exchange money. In general, credit cards are not widely accepted in Iran. The best way is to have cash with you. The rate of exchange goes through very little fluctuations everyday.
