Over here in Europa you get bombarded with the monthly/yearly subscription. And for companies it makes much more sense, regarding cashflow/projection etc.
A single ticket has to be printed and used in the space of a few hours. A monthly pass can be printed at any time and sold until the beginning of the month, for a much higher price. Much more risky for the transportation company.
Isnt it that ticket price should somehow decrease?
Ie. the end of the month November, not the end of December. I suppose you could also sell the remainder at a discount in December.
One bus company embedded the signing key for the ticket app in the app so that was not a good way of precenting fakes,
Much higher value train tickets are widely used in printed form and forgeries have not been a problem.
