they also say you should swipe your oyster as you enter a station even if
the gates are open, or you might have a problem at your exit station.
my local station gates are always open and I never swipe it, and I have had
no problems on exit.
I think it is a case of 'Big Brother wants to know where you are and where
you are going'.

That is fine - but this is followed by:

"Customers with Oyster Cards charged with Travelcard Season tickets
not valid at Finsbury Park (Zone 2) are also advised to touch their
cards on the validators"

Can someone explain what this is about?

They have these machines on the platforms at Highbury & Islington too.
Don't understand why anyone would swipe an Oyster or give up a Carnet
when they aren't forced to.

BTW hos do Oysters work on National Rail services?
