WIR Bank
The WIR Bank, formerly the Swiss Economic Circle (German: "Wirtschaftsring-Genossenschaft"), or WIR, is an independent complementary currency system in Switzerland that serves businesses in hospitality, construction, manufacturing, retail and professional services. WIR issues and manages a private currency, called the WIR Franc, which is used in combination with the Swiss Franc to generate dual-currency transactions.
European integration
The European Economic Area (EEA) agreement allows Norway, Iceland and Liechtenstein to participate in the European Single Market without joining the EU. The four basic freedoms apply. However, some restrictions on fisheries and agriculture take place. Switzerland is linked to the European Union by Swiss-EU bilateral agreements, with a different content from that of the EEA agreement.
The Eurozone refers to the European Union member states that have adopted the euro currency union as the third stage of the European Economic and Monetary Union (EMU). Further, certain states outside the EU have adopted the euro as their currency, despite not belonging to the EMU. Thus, a total of 25 states, including 19 European Union states and six non-EU members, currently use the euro.
