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.
Swiss identity card
When the 1977 version of the Swiss identity card was issued, the first issue was still printed in German, French, and Italian. Later on, Romansch was added to the identity cards (along with English) after it became a national Swiss language in the new 1999 Swiss constitution that followed the 6 March 1996 referendum of Swiss voters.
