Can the BOP and HFC be kept on each of our phones (husband and me) in the apple wallet or in my SBB.ch account? Do each of us need our own sbb.ch account? The BOP website says to print the pass, so I wasn't sure if we have to keep a paper copy on us.
Can we purchase one or both passes at ticket machines and/or on sbb.ch on the day of arrival to ZRH? Is there a benefit to purchasing via ticket machine vs online?
Thank you!
