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.
Franc
The countries that use francs include Switzerland, Liechtenstein, and most of Francophone Africa. Before the introduction of the euro, francs were also used in France, Belgium and Luxembourg, while Andorra and Monaco accepted the French franc as legal tender (Monegasque franc). The franc was also used within the French Empire's colonies, including Algeria and Cambodia. The franc is sometimes Italianised or Hispanicised as the "franco", for instance in Luccan franco.
