The unit of currency is the Iranian Rial (IRR) which is divided into 100 dinar, but the Toman is used by Iranians today as the equivalent of ten Rial. Most Iranians state the value of things in Toman instead of Rial. Prices are most often marked in Toman, with 1,000 or 1,000,000 Toman equivalent to 10,000 or 10,000,000 Rial respectively. It is best to travel with US Dollars, which can be exchanged upon arrival in the airport or banks in big cities or at street rate at street outlets. An increasing number of mid-range hotels and all top-end establishments accept Visa and MasterCard. Some of the more expensive Iranian hotels charge in US Dollars.
