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.
Postage stamps and postal history of Switzerland
Swiss stamps are inscribed with the word "Helvetica", rather than "Schweiz", "Suisse" "Svizzera", or "Svizra". With four official languages-German, French, Italian, and Romansch. The Swiss would have had to put all four languages on each stamp, quite a problem to overcome with such limited space on a stamp.
