Apple Pay debuted almost 10 years ago to the day, and Apple is marking the occasion by rolling out some features it revealed at WWDC. If you have iOS 18 or iPadOS 18 installed on your iPhone or iPad, you'll now be able to use the payment service on third-party browsers on those devices, as well as desktop computers. In the latter case, you'll be asked to scan a QR code with your iPhone or iPad to complete the payment. However, Apple says the feature is only available in select markets.
