Anybody heard of any plans for Weekly capping ?

Presumably it would have to operate at a database level rather than from
the data held on the card, but surely this isn't beyond the ability of
TfL DBAs ??

It does sound like it ought to be feasible though rather than spend capping
I should imagine it would have to be done on a refund basis. If that is the
case they might as well do it on a monthly basis or even a quarterly one.
I'd certainly like to see it, though it is well behind roll out of Oyster on
National Rail on my wish list.
