London's transport network (TfL) says it works closely with Apple to activate a new Apple Pay Express Transit feature. Apple first introduced Express Transit in iOS 12.3 earlier this month so Apple Pay users only keep their devices on transit terminals without having to approve via touch ID or face ID. It is a very useful feature that allows faster access to subway or train stations, and is extremely fast in terms of approval. It also works on an Apple Watch without having to press the side button.
While Express Transit is working for Suica cards in Japan, the TriMet in Portland, New York's MTA (starting tomorrow) and Chinese transit cards in Beijing and Shanghai, London are missing from the list for now. "We have positive discussions with Apple to enable express delivery on Apple devices on the TfL network," a TfL spokesman said in a statement to The Verge . "More information on timing and plans will be available on a future date."
When the Express Transit feature is enabled for London, you can choose a card on the Apple Watch or iPhone that is specifically enabled to tap and go on Oyster terminals. It will not require any Face ID or Touch ID authentication, but this will only work on supported public transport readers, so the security implications should be quite low.
