How to rent a bicycle with Swiss Travel Pass QR on mobile phone or printout?

If I need to rent a bicycle will paper QR code allow me to do that? Or do I need to have physical card?

The Swiss Travel Pass and the SwissPass is not the same. The former is for tourists, the latter for residents.

The Swiss Travel Pass comes as paper ticket when being purchased at the railway station ticket offices or as e-ticket when being purchased online.

Kind regards,

I checked with SBB.
The Swiss Travel Pass does not grant a discount when renting a bicycle.
