Hello,I have an account linked to my Swisspass with Half-Fare contract, but everytime I show the ticket purchased on the CFF site, I am asked to show the Swisspass too.So is the following true or not?https://www.sbb.ch/en/travelcards-and-tickets/buying-options/online.html"If you have a Half-Fare travelcard on the SwissPass and have purchased a ticket at a reduced price, from 1 August 2016, it is sufficient to only show the ticket on the app. A precondition of this is that you have linked the personal details from your online account with SBB to the SwissPass account. Then it is not usually necessary to show the SwissPass card. If no online connection is available when the check takes place, you will need to show the SwissPass or a valid official ID document." Cris
