As of 2014, Switzerland's currency is the Swiss franc, not the euro. Because the countries surrounding Switzerland use the euro, many businesses, especially those near the country's borders, accept euros.
The Swiss franc is the currency of Switzerland and Liechtenstein, the only two European countries that still use francs. Switzerland isn't a member of the European Union (EU). Not all EU member countries use the euro, and some countries that use the euro aren't members of the EU. Although the United Kingdom, Denmark and Sweden are EU members, they have retained their own currencies as of 2014. Andorra, Kosovo and Monaco use the euro but aren't EU members. In 1999, 11 countries adopted the euro, and the first coins and banknotes appeared in 2002.
