Hello Moiceessie41
There is no clear answer to your question as we do not know whether you are a resident of Switzerland, or not. If you are a resident, the Half Fare Card will renew automatically; you will receive an invoice for the renewal.
If you live abroad, please get in touch with SBB by phone: +41 51 225 78 56 (24/7). On this platform, we are unable to treat any requests involving personal information.
Best wishes,
Roland
