Apple Watch users can now officially download watchOS 4.2 offering support for Apple Pay Cash.
To download the new software, head to the companion Watch app on an iPhone. On the My Watch tab, select General > Software Update. The watch will need to be connected to Wi-Fi, on a charger, and charged to at least 50 percent.
Using watchOS 4.2, users can send and receive money through Messages using the new Apple Pay Cash feature that also arrived in iOS 11.2. It’s currently only available in the United States.
