Yes, in 2026, the Swiss Travel Pass is primarily a digital product and can be easily stored on your phone. When you purchase the pass online through the SBB (Swiss Federal Railways) website or a licensed partner, you receive a PDF containing a QR code via email. You can simply save this PDF to your files, take a screenshot of the QR code, or add it to your Apple Wallet or Google Pay for quick access. However, the most integrated way to use it is by logging into the SBB Mobile app. If you create a "SwissPass" login before purchasing, the pass will automatically appear in the "Tickets & Travelcards" section of the app. This is particularly useful for the "Swiss Travel Pass Flex," as the app allows you to activate your specific travel days with a single tap before boarding your first train of the day. Remember that you must always be able to show a valid photo ID (like a passport) alongside the digital QR code when the conductor scans it. Also, ensure your phone is sufficiently charged; if your battery dies and you cannot present the pass, you may be issued a "fine" that requires a visit to a ticket office later to resolve.
