The currency used is the Swiss Franc (CHF). The Euro is generally accepted in large stores (Migros, Coop, etc). Service providers such as SBB (railway company), CGN (Compagnie Générale de Navigation), La Poste, some restaurants and museums also accept them, although change can be given in CHF.
It is possible to exchange your money in CHF and other currencies (€, $, £, ¥, CAD, AUD...) at the various banks, at the Post Office, at the SBB stations and directly at the banks' cash machines.
The main credit cards (Visa, Mastercard, Eurocard) are accepted as payment in large stores. However, in small shops and restaurants, it is preferable to pay with debit cards (EC). Most of the payment methods are indicated directly at the cashier's desk or on the entrance door of the establishment.
A value added tax (VAT) is included directly in the purchase price.
