Economy of Liechtenstein
The economy of Liechtenstein is based roughly equally on services (especially financial services) and industry, with a small but significant agricultural sector. The country participates in a customs union with Switzerland and uses the Swiss franc as its national currency. It imports more than 85% of its energy requirements. Liechtenstein has been a member of the European Free Trade Association (EFTA) since 1991 (previously its interests had been represented by Switzerland). It also has been a member of the European Economic Area (EEA) since May 1995 and participates in the Schengen Agreement for passport-free intra-European travel.
Banknotes of the Swiss franc
During the 19th century the cantons (states) of Switzerland had the right to print their own notes. Following the law of 8 March 1881 the Swiss National Bank had the exclusive right to issue banknotes in Switzerland. Its first notes were issued in 1907. Since then, nine series of Swiss franc notes have been printed, six of which have been completely released for use by the general public, and a new series started being released in 2016.
