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.
Swiss franc
In 1798, the Helvetic Republic introduced the "franc", a currency based on the Berne thaler, subdivided into 10 "batzen" or 100 "centimes". The Swiss franc was equal to grams of pure silver or French francs.
