Currency
The official currency is Iranian Rials (IRR), which has an exchange rate of between 30,000 – 40,000 for EUR 1. Nobody uses Rials however, everyone uses Toman (which is 10 Rials). So EUR 1 is around 3,000-4,000 Tomans
Oanda has information on the latest exchange rates and features an online currency converter.
Your credit/debit cards won’t work. Local cards are accepted in many places but cash is accepted everywhere. Useful official bank notes are 1,000 Toman (10,000 Rials) 5,000 Toman (50,000 Rials) and 10,000 Toman (100,000) Rials. You will also see a lot of pinkish money like travellers cheques that are 50,000 Tomans (500,000 Rials). These are worth around EUR 13 or so.
You can’t exchange money easily in town, or anywhere outside of Iran. Your best bet is to exchange enough money at the airport. Your hotel will also exchange EUR or USD, but at a very bad rate.
