The Swiss franc, or simply the franc, is the currency and legal tender of Switzerland and Liechtenstein. It is also legal tender in the Italian exclave of Campione d'Italia, which is surrounded by Swiss territory. The Swiss National Bank (SNB) issues banknotes and the federal mint Swissmint issues coins. It is also designated through the currency signs Fr. (in German), fr. (in French, Italian, and Romansh), or CHF (in any other language), which stands for Confoederatio Helvetica Franc. This acronym also serves as the ISO 4217 currency code, used by banks and financial institutions. The smaller denomination, a hundredth of a franc, is a Rappen (Rp.) in German, centime (c.) in French, centesimo (ct.) in Italian, and rap (rp.) in Romansh. The official symbols Fr. (in German) and fr. (in the Romance languages) are widely used by businesses and advertisers, including in English. However, according to Art. 1 SR/RS 941.101 of the federal law collection, the internationally official abbreviation – regardless of the national languages – is CHF, which is also to be used in English; respective guides also request that the ISO 4217 code be used. The use of SFr. for Swiss Franc and fr.sv. are outdated. As previously indicated, the Latinate "CH" stands for Confoederatio Helvetica; given the different languages used in Switzerland, Latin is used for language-neutral inscriptions on its coins.
