Whilst this is probably the case from a legal perspective, I wouldn't be so
sure technically. I had heard that in trials for either the original paper
based Metcards or either the upcoming Metcard Xpress (coming
soon...soon...soon...well hopefully sometime before I die of old age), the
users were traced by ticket number as to when they had used their ticket.
This would make sense as it would be simple to track a ticket number in a
database I would have thought.
