Travelers to Switzerland must ensure they have a valid passport with at least six months validity beyond their planned departure date. Visa requirements vary depending on nationality, so it's important to check with the Swiss embassy or consulate in your home country. As for vaccinations, there are no compulsory vaccinations for visitors to Switzerland, but it's always a good idea to be up to date on routine vaccines. Additionally, it's advisable to check for any travel advisories and entry restrictions for foreign visitors prior to your trip.
The accepted currency in Switzerland is Swiss Franc (CHF). It's advisable to check the current exchange rates and compare them with your local bank rates before exchanging currency. ATMs are widely available, and credit cards such as Visa, Mastercard, and American Express are widely accepted. However, it's always good to carry some cash for smaller purchases. Mobile payment options like Apple Pay and Google Pay are becoming increasingly popular in Swiss shops and restaurants.
