You should touch every pink Oyster reader that you encounter during your journey. It will either have no effect on the fare that you pay, or it will reduce your dare, it will never cause you to pay a higher fare.

Wrong. You should only touch the ones specified by TfL in the Single
Fare Finder.

I am aware of an instance where people touched every pink validator on
their route and one was ignored and the people were charged as if
travelling via Zone 1.


Dare I suggest that in that instance the touch on the relevant pink
validator didn't register (i.e. they didn't get a green light)?
