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.
Liechtenstein
Liechtenstein participates in a customs union with Switzerland and employs the Swiss franc as the national currency. The country imports about 85% of its energy. Liechtenstein has been a member of the European Economic Area (an organization serving as a bridge between the European Free Trade Association (EFTA) and the European Union) since May 1995.
