We are going to get a Half Fare Travel Card for 1 month in Switzerland. But in addition, I was just reading about the Half Fare Travel Card PLUS: https://www.sbb.ch/en/tickets-offers/travelcards/half-fare-travelcard-plus.html
It looks like once a Half Fare Travel Card is purchased, I can go onto this website and deposit money, from which my fares are paid while travelling. Once the amount deposited is used up, a bonus amount is added.
Question: Can anyone verify that I've understood correctly that I could still get all the usual Half Fare Travel Card discounts on trains and Berner-Oberland lifts etc, and also benefit from the $ bonus offered this PLUS program?
Also, how long has this been around? It says 'new' on the website.
