Hello Lleellaucis19
Are you now talking about the Swiss Half Fare Card or the Half Fare Card?
Yes, EasyRide can be used even with the Swiss Half Fare Card. The Swiss Half Fare Card offers the same advantages as the Half Fare Card.
E-Tickets and EasyRide need your physical passport or ID (no paper copies / no photos of it on smartphones).
However, I do not recommend EasyRide for tourists for longer trips. It might be a good thing for rides within a city where the zone tickets can be overwhelming.
For day trips or mountain excursion trips, however, you should look at Saver Day Passes, Day Passes, or even tourist offers and tailor-made tourist passes.
Kind regards,
Roland
