Microsoft has announced that support for the Payments Request API is coming to Microsoft Edge in the upcoming Creators Update. Available for testing now in Creators Update preview builds, the Payments Request API will work with Microsoft Wallet on both PC and Mobile to make checking out on websites that opt to support it.

From Microsoft:

In Microsoft Edge, the Payment Request API connects to Microsoft Wallet (with the user's permission), allowing easy access to payment information associated with the user's Microsoft Account. Because payment information is securely saved in a digital wallet, shoppers don't have to navigate through traditional checkout flows and repeatedly enter the same payment and shipping address information repeatedly. The wallet can provide a faster and more consistent experience across websites, which saves shoppers time and effort by allowing them to securely share saved payment information.

The Payments Request API was designed in concert with other members of the W3C Web Payments Working Group in an effort to standardize a better payments experience across browsers and merchants. Other browsers are also starting to implement the API, with Google, for example, adding it to Chrome 53 for Android earlier this year.

If you're on Windows 10 Insider build 14986, you can already start experimenting with the Payments Request API. It's also worth noting that a toggle for the experimental Web Payments API exists in about:flags in Edge (seen in the screenshot below), and has been there for months.
