The currency and legal tender of Switzerland is the Swiss franc (Sfr), which is divided in 100 rappen. There are banknotes of 10, 20, 50, 100, 200 and 1000 francs. The coins in use are 1,2 and 5 francs as well as 5, 10, 20 and 50 rappen. You can change your money at UMC Change, Frankenstr. 5 (tel. (+41) 41 211 00 50, C-4, www.umc-change-lu.ch, just next to the station) or at the SBB Change at the train station or any of the banks. Or just withdraw Swiss francs with your Maestro or your Plus card from one of the ubiquitous ATM’s. Credit cards are widely accepted - both in shops and restaurants. Service is always included. At a restaurant however, if you were happy with the service, leave 5-10% of the bill as a tip.
