Swiss franc
The Swiss franc is the currency and legal tender of Switzerland and Liechtenstein and also legal tender in the Italian exclave of Campione d'Italia. Although not formally legal tender in the German exclave of Büsingen am Hochrhein (the sole legal currency is the euro), it is in wide daily use there; with many prices quoted in Swiss francs. The Swiss franc is the only version of the franc still issued in Europe.
Switzerland
Switzerland has four national languages: mainly German (spoken by 62.8% of the population in 2016); French (22.9%) in the west; and Italian (8.2%) in the south. The fourth national language, Romansh (0.5%), is a Romance language spoken locally in the southeastern trilingual canton of Grisons, and is designated by Article 4 of the Federal Constitution as a national language along with German, French, and Italian, and in Article 70 as an official language if the authorities communicate with persons who speak Romansh. However, federal laws and other official acts do not need to be decreed in Romansh.
