Halfare Travelcard Plus
The credit acquired through the Half Fare Travelcard PLUS is not currently compatible with FAIRTIQ during the initial stage of the offer.
However, at a later stage, the credit obtained via the Half Fare Travelcard PLUS should become usable on FAIRTIQ.
Note: naturally the Halffare Travelcard itself can be added to FAIRTIQ. See Swisspass, Half-Fare, Travel Cards & Passes
