But a possible fraud does spring to mind. You have a 2 to 6 Travelcard in
your Oyster. You swipe when you enter at Finchley Road, and again when you
leave at Earls Court. The system doesn't know if you have travelled through
Zone 1 or via Rayners Lane, unless it checks journey times.... can it do
that? Any RCI who caught you in Zone 1 wouldn't be able to bust you, since
you could legitimately be planning to exit at a Zone 1 station and be
debited for the extension.

I'd would have thought that the system should pick that up:

a) Your last validation point was at Finchley Road.
b) You could make the journey via Rayner's Lane and be ok - but it
looks unlikely!

c) Gates raise 'possible dumbell' flag - SA asks where ypu've been....


No real change from now....
