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.
Coat of arms of Switzerland
Alternative shapes of the heraldic shield were also in frequent use, and still remain in use in spite of the 2017 legislation. 
A frequently seen shield shape is the "Iberian" or "curved" type, specifically used to mark Swiss embassies and border crossings, and also used on the five franks coin. 
Another frequently seen variant is a Renaissance-style articulated shield, shown as being held by the national personification Helvetia on the ½, 1 and 2 franks coins.
