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.
