Sorry, I was pointing out that it was very difficult to get a smart
card transport ticket system to work. Reading the cards is not that
hard but managing lots of data from lots of different readers is.

Yes,one of the lessons from the failure of such systems seems to be
that you need to rationalize the fare system as part of implementing
the smart card. Assuming that because it is computerized, it can cope
with arbitrarily complex tickets does not work.

If the wireless network could be extended out of the bus depot, it
would make the implementation easier. As an example, there is a WiFi
network in the Sydney CBD, set up for the Emergency Warning and
Intercommunication (EWIS) Alert system installed for the APEC meeting
Perhaps that could be used to communicate to busses. Or the
electronic signs installed at bus stops to display live route data
could double as access points. The bus could update data at each bus stop.
