Hello peterschneider
Thank you for your question.
The SwissPass is a “carrier”, only a card. It depends which travelcard you activate on it: it can be a GA, a half fare travelcard and so on. It is a Swiss product.
If you wish to travel to France you need a valid ticket.
Please contact our SBB Contact Center (0848 44 66 88, CHF 0.08/min) for more information.
I wish you a pleasant day.
Kind regards,
FatimaH
