paper receipt or not - but if that is what it was 10 years ago, then that is what it was - and probably ok at the time (for ticket inspection).
from what watso can see these days, is that most people seem to simply swipe a card. frankly, watso has no idea how it all works out - because he simply does not know... eg a person buys a bus ticket, and from memory, that lasts a couple of hours on the transperth system - so maybe a bit of honesty and inspection comes into play
