Microsoft has a new app in the store designed to make it easier to spend and spend over the holiday season.
Microsoft Pay appears to be a replacement for Microsoft Wallet and brings support for the Payment Request API to Edge.
This means a website can request a payment for an item, and the app will be launched with your details already filled in, ready to approve the spend.
While theoretically available for Windows 10 and Windows 10 Mobile, it requires a minimum OS version of 16299 (Redstone 3), which never made it to Windows 10 Mobile.
Payment Request API is a W3C standard, meaning it does not depend on online stores adopting Microsoft technology, meaning it may soon become much easier to pay on the internet, even from Edge.
The app can be seen in the Store here, but be warned that clicking on the link appears to cause the app to be installed automatically with no visible UI. To see it in action you can visit a test site here.
