The change means travellers no longer have to carry their physical SwissPass card with them. Details of their half-price (halb-tax/demi-tarif) or GA travelcard will instead be stored electronically on their smartphones.
To take advantage of the new electronic SwissPass straight away, you need to download the SBB Mobile Preview app, which is used to test to new features before they are included in the main SBB app.
After downloading the app, you will need to input the details of your travelcard.
Ticket inspectors will then be able to scan the QR code on your phone to check you have a valid half-price or GA travelcard.
The electronic SwissPass function will be included on the standard SBB app at a later date which is yet to be decided.
The introduction of an electronic SwissPass is one of the suggestions for improving the SBB recently made by readers of The Local.
Other suggestions from our readers included a blanket ban on smoking on train platforms and eliminating the half-price travelcard in favour of cheaper prices across the board.
