The currency of Tunisia is the Tunisian Dinar (Dinar tunisien). The abbreviations DT or TND are used to represent it. One Dinar is made up of 1,000 milim or millimes.
One important thing to know about the Tunisian Dinar is that it is a closed currency. This means that it is not available outside the country. Travelers going to Tunisia may not be able to obtain the Dinar before entering the country. They will need to carry other currency such as US Dollars, Euros, or British Pounds, and may get them converted after landing in Tunisia. Similarly, it is mandatory for travelers to convert back any Tunisian currency that they may have (including coins) into any other currency before they leave the country. Carrying Tunisian Dinars outside the country is an offense and visitors are sometimes searched for Dinars before they leave. The business establishments in the country accept all major credit cards, though.
Tunisia is not the only country to call its currency the Dinar. Algeria, Kuwait, Libya, Iraq, Macedonia, Bahrain, and Serbia also use currencies which are called Dinar. The word Dinar is of Arabic origin. It is believed to have been derived from the Greek word Demarion which referred to a silver coin which was used around 211 BC.
In 1960, the Dinar was introduced as the official currency of Tunisia replacing the Franc which had been the principal currency of the country. Currently, Dinar notes of 10, 20, 30, and 50 denominations are in circulation.
