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.
Sweden
Sweden maintains its own currency, the Swedish krona (SEK), a result of the Swedes having rejected the euro in a referendum. The Swedish Riksbank—founded in 1668 and thus the oldest central bank in the world—is currently focusing on price stability with an inflation target of 2%. According to the "Economic Survey of Sweden 2007" by the OECD, the average inflation in Sweden has been one of the lowest among European countries since the mid-1990s, largely because of deregulation and quick utilisation of globalisation.
