We hear all the time that machines can only store a limited amount of "top
up" data as the details can't be access online in real time.

Yet here we are being told that the number of the (cards of the) thousand
or
so people in the trial are either available in real time or are stored in
every machine on the network.


The "not in real time" difficulty was for buses.

I imagine that the full scheme will store a hot card list for every gateline
cluster so checking a good card list for the pilot is easy enough and a
useful test.
