Microsoft Wallet has changed its name to Microsoft Pay. Thanks to a tip from a OnMSFT reader (via Aggiornamenti Lumia), Microsoft Pay is available to use at any online store that supports the "Payment Request API" in Microsoft Edge. Microsoft Pay already has some stiff competition on iOS and Android; with Apple Pay, Google Pay, and Samsung Pay.
Microsoft has a test website available for developers to try out Microsoft Pay. Microsoft explains how Microsoft Pay will work:
"In Microsoft Edge, the Payment Request API shows the Microsoft payments user experience and, with the user’s permission, allows easy access to payment and address information associated with the user’s Microsoft account. The wallet can provide a faster and more consistent experience across websites, which saves shoppers time and effort by allowing them to checkout with their saved payment and address information."
Microsoft Pay was included in the Windows 10 Creators Update, but only now Microsoft Wallet has updated to reflect the name change. Microsoft Pay is developed for use with Windows 10 and Windows 10 on ARM devices.
Not even the Microsoft Store is allowing you to pay with Microsoft Pay yet. For now, it looks like Microsoft is just preparing it for full deployment. Maybe we'll see it on the first Windows 10 on ARM device?
Try Microsoft Pay in the Microsoft Store.
Thanks for the tip, Simon!
