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.
Austrian schilling
Although the euro became the official currency of Austria in 1999, euro coins and notes were not introduced until 2002. Old schilling denominated coins and notes were phased out from circulation because of the introduction of the euro by 28 February of that year. Schilling banknotes and coins which were valid at the time of the introduction of the euro will indefinitely remain exchangeable for euros at any branch of the Oesterreichische Nationalbank.
