On Monday 28 March, the Windsor and Henley Thames Valley Branches started accepting contactless 'Pay as You Go' partially ending the oddity of not being able to use contactless payments away from the main arm of the GWML. Windsor & Eton Central, Wargrave, Shiplake and Henley-on-Thames all now appear on the TfL Single Fare Finder although paper tickets could still represent better value for money in certain cases. Contactless acceptance at Furze Platt, Cookham, Bourne End and Marlow is expected to follow shortly.

But not Oyster cards, I assume?

No, sadly not. Existing system limitations parts of the Oyster card system mean that it can only accommodate 15 fare charts IIRC. All bar one are currently in use.

While the chip in Oyster cards only has 16 charts (0-15), I can't see how that would directly affect PAYG since that (ought to be) just clocking the entry/exit points and calculating it later...unless the O system does that in the exit gate and is zone-based instead of point-to-point based.
(z dived further down the rat-hole of transit payment systems...)

I guess it has to know zones to calculate daily caps?

Introducing updated Oyster cards for everyone would be difficult and expensive. |

We are already on the second version of Oyster cards though, my original one stopped working and I was told it was because it had the old chip in and I needed a new one.
Edit to add: Wasn't it a switch between MiFare and Desire or something?

I believe it's down to the back of house capabilities when applied to existing Oyster cards. I think you're right on that, it would be the different process flows of stored-value in the card vs accumulating transactions and batch-processing them all after hours. I expect that it would be possible to simply use the Oyster as a token, like a touch card, but that would require a much larger back-end to process the transactions.
IIRC, the Oyster back-end is operated under contract by to ?? and the touch-card PAYG directly by TfL. Yes/no?
