>> Also, does any kind of photo identity proof will work alongside STP or it has to be a passport. The thing is I wouldn’t prefer carrying the passport everywhere.
On your Swiss Travel Pass it will state ONLY VALID WITH YOUR PASSPORT/ID
This will be the passport or official ID that you provide when buying the Swiss Travel Pass, the number of which will be printed on your pass.
Conductors will not ask to see your passport on every trip. In 7 weeks of daily travel in 2016, I had to produce my passport only 3 or 4 times. However, if they do ask to see it, and you don't have it, you are regarded as travelling without a valid ticket.
