C'mon, luddites. You know this is best system from the law abiding passenger POV. You just install app, link credit card, and IRS done. You would never ever need to care about paying, buying tickets on time, not forgetting them at home etc etc. Stations can remove turnstiles, making entrances wider a d more friendly.
And from needed infrastructure it's already in place, cameras are everywhere and everyone has smartphones. You just need to link them to servers running billing software.
This is example of technology really making peoples life easier and more enjoyable.
