In Switzerland there are no gates or a need for "showing a card/ticket to an operator, or otherwise proving you have, in fact, purchased a fare".
You just enter the bus/train/tram vehicle. Maybe a ticket controllant comes, maybe not (most often they dont come and check)
EDIT: To get a ticket you simple open the app and "check in". When you leave the transport you open the app and "check out". At the end of the day the system calculated the cheapest ticket for you based on that 24h period. This works across the entire country. From local buses to high speed intercity rail
