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.
Basel Badischer Bahnhof
The Badischer Bahnhof is located on Swiss territory, but due to the 1852 treaty between the Swiss Confederation and the state of Baden (one of the predecessors of today's Germany), the largest part of it (the platforms and the parts of the passenger tunnel that lead to the German/Swiss checkpoint) is treated as an inner-German station and is operated by the Deutsche Bahn. The shops in the station hall, however, are located in Switzerland, and the Swiss franc is used as the official currency there (although the euro is universally accepted).
