The Swiss Half Fare Card (marketed primarily to international tourists) is valid for exactly one month from its chosen start date. During this 30-day period, the card entitles the holder to a 50% discount on almost all public transportation in Switzerland, including the extensive national rail network (SBB), postal buses, lake ferries, and even most high-altitude mountain railways and cable cars. This is a popular choice for travelers who plan to stay in one region or who don't intend to travel every single day, as it significantly reduces the cost of point-to-point tickets. It is important to distinguish this from the "Half-Fare Travelcard," which is a year-long subscription typically used by Swiss residents. The tourist version can be purchased online as an e-ticket and must be presented alongside a valid ID and the discounted ticket during inspections. If you are traveling with children aged 6 to 16, you can request a complimentary Swiss Family Card when purchasing your Half Fare Card, allowing the children to travel for free as long as they are accompanied by at least one parent holding the valid pass.
