The Swiss Franc
Please note that Switzerland remains with the Swiss franc. While Switzerland is not a part of the European Union and thus is not obliged to convert to the Euro, many prices are nonetheless indicated in euros so that visitors may compare prices. Merchants may accept euros but are not obliged to do so. Change given back to the client will most likely be in Swiss francs.
The official ISO code of the currency used by banks and financial institutions is “CHF”, though most users of the currency, including advertisers, and stores generally use the “Fr.” abbreviation. Some users also write “SFr.”. The smaller denomination, which is worth a hundredth of a franc, is called Rappen.
Credit cards
All popular credit cards such as Diners, Euro, VISA, Mastercard and American Express card are accepted widely in shops, airports, railway stations and other payment centers across Switzerland.
