Speaking of automatic barriers, I passed through KX today and saw
scanners fitted to them at the gateline, in addition to Oyster card

Will this become standard throughout London and eventually the UK?

I hope so... contactless and barcode with some proportion
contactless-only, I don't see the need for magnetic any more, paper
tickets could then be as large as necessary to get the required
