Tunisian dinar
It is a criminal offence in Tunisia to import or export dinar. Every year, each citizen can convert into foreign currency up to 6,000 Tunisian dinars before departure from the country. Therefore, prices at duty-free shops are in convertible currencies such as euros, US dollars and British pounds. There are many converting ATMs in the country for tourists.
National language
The official language of the Tunisian state is Arabic. However, that language is not the mother tongue of the population or used to communicate between Tunisian people, instead Tunisian Arabic plays these roles and is the national language of Tunisia. Also, even without an official status, French is also used extensively in its written and spoken form in the administration, education and business environment and known by 63.6% of the population. Also Berber minorities in the south-west and on Djerba Island use the Tunisian Chelha language to communicate between themselves.
