Because the data is on your card. Otherwise, every time you touched
in on a 'bus, the system would have to interrogate a central database
to see if you had credit.

I see. But that means that if you lose your Oyster card and report it
lost to invalidate it, anyone finding it can still use it on a bus, and
indefinitely I guess, unless the bus reader downloads numbers of lost or
stolen cards from time to time?

I imagine something like this must occur. But that's rather different
to asking a 'bus reader to contact Oyster Central in real time as each
passenger touches in.

I think it does happen, I was on a bus a couple of days ago when I heard
the driver telling a woman that her freedom pass had been cancelled and
he did not know why, but she should contact them to find out

Urm, no.

The bus ETMs have local hotlists which get updated periodically.
