The points make it easy to build in the service fee. Public transit here maintains an “account balance” in USD, you set the max and when your account dips below what is required for fare it refills to that max.
Steam does some something similar with an account balance but I don't think it refills. I believe a lot of businesses have a similar concept. I think you can maintain an account balance at Amazon (and probably other retailers) too.
