Hello Keawhaungue61
I apologize for the inconvenience you are experiencing with your Halbtax Plus. The error code NTHTA-2 indicates that the purchase with the Halbtax Plus is only possible for the logged-in user. If you are trying to purchase a ticket for someone else, the Halbtax Plus payment method will not be available on SBB.ch, and you will receive an error message on SBB Mobile.
Regarding the issue with Apple Pay (Error code: NTTIF-2000), I’m sorry to inform you that Apple Pay is not currently supported for Halbtax Plus payments2.
Additionally, if the ticket machine at the station is not accepting any of your cards, I recommend trying another payment method or contacting your bank to ensure there are no issues with your cards.
I wish you an excellent afternoon.
Greetings
RahelW
