Can you explain what you mean by "so much human intervention"?

presume he means when buying the card, and when spending hours talking
to the helpline to sort out unresolved journeys etc.

Plus of course the effort of getting printouts for "expenses purposes"
when all you need do with a paper ticket is hand in the ticket itself.

Huh ?

Has it escaped your notice that the final exit gate swallows your paper
ticket ?

First time this made a difference to me was attending a job interview at the
Met Office.

Bracknall station had just been fitted with barriers.

Before mag stripe tickets the the barrier attendant took your ticket.
