Apple is redesigning the Apple Pay payment sheet for websites and apps in iOS 27. Shoppers will be able to swipe between cards, see more card-specific information such as rewards and balances, and choose a payment method with less friction. The redesign is still a preview: Apple says it is coming this fall, and final availability will depend on supported cards, merchants, regions, and the release build.
