With a validator equipped station Travelcard holders
who are "in zone" don't have to swipe their Oyster
card but if you are out of zone you do for the
purposes of calculation of auto ticket extensions.

I see no way that LU can prevent fraud. You can travel anywhere you like on
the system with a one-zone travelcard, and then when you get to your
destination, if the gates are active, you swipe and have your extension
deducted... if the gates are inactive, you just walk out and you have no way
of getting caught. If any RCI stops you en route out of your travelcard
zone, you just say you are going to swipe for the extension at your
journey's end.

But this is no different from the magnetic ticket system.
CofC state that you must have a ticket to cover the whole of the journey
you are making.
A RCI finding no Pre Pay balance on an Oyster could either issue a paper
extension ticket or a £10.00 Penalty Fare.
