Well unless the RID has a realtime radio link to the main computer I don't

Mobile data hardware and airtime is dirt cheap these days, so I'd not be
at all surprised to learn that ticket inspectors' hand-held devices can
talk to head office in real time.
Maybe. Though they seem to work rather quicker than I'd expect if there was
a round trip request via a GSM link. Also I've seen them being used in the
DLR tunnel to Bank where there's no chance of a signal (I assume DLR use the
same system). Quite why they were bothering to do a revenue check just before
one of the few stations on the DLR where you *can't* get out without a ticket
is anyones guess.
