Hello Thongouzoo73
In this case, you must buy tickets in two transactions:
— Swiss tickets from Zurich to Basel with the Half Fare / Family Card
— French tickets from Basel to Paris without the the Half Fare / Family Card
Seats will be reserved from Basel but you can board the TGV in Zurich.
However, it is probably cheaper to buy tickets from Zurich to Paris without the Half Fare / Family Card if you choose discounted prices (semi flexible or non flexible tickets) and you take a direct TGV from Zurich to Paris.
Kind regards
