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.
Austrian schilling
Although the euro became the official currency of Austria in 1999, euro coins and notes were not introduced until 2002. Old schilling denominated coins and notes were phased out from circulation because of the introduction of the euro by 28 February of that year. Schilling banknotes and coins which were valid at the time of the introduction of the euro will indefinitely remain exchangeable for euros at any branch of the Oesterreichische Nationalbank.
