Swiss francs...

Hello nandita. You can pay by credit/debit card at many places, so you won't need that much cash. You can extract money in Swiss francs from one of the many ATM's and/or exchange your foreign currency at banks or at larger railway stations. The current exchange rate will apply. Banks may offer the best rates, but I'm not sure about that.

By the way nandita, would you try not to use 'text language' and abbreviations, as asked for in our forum rules? Some of your posts may be hard to read for forum visitors. Thank you in advance :-)!
