NFC Tap to Pay is coming to Windows 10 Mobile with Microsoft Wallet 2.0

The new Wallet 2.0 app is broken into two areas:
Credit or debit card
Loyalty or membership card

When first launched Wallet will check your Microsoft Account for any credit cards already linked (e.g. for the Store) and import those for Tap to Pay. All of this is optional, of course, and interestingly Lumia 950 even utilized Windows Hello for my account authentication, which was a nice touch.

Regarding the loyalty card area, users can pick from a list of companies and either scan the card or enter it manually. A barcode is then generated for easy scanning and users can pin those individual cards to their Start screen for quick access.
If a business is not listed, users can create their own barcode by entering in the information for the card.

I expect this list to grow and since Wallet 2.0 is just an app Microsoft can make easy additions and fixes whenever they want.

Does it work?
So, the million dollar question is does it work?
As a sacrifice, or rather, experiment I went to my local McDonald's who are known to use Tap to Pay. I ordered up a Double Quarter Pounder with cheese to celebrate because I have not eaten at McDonald's in about a decade. At the moment of truth, I tapped my phone to the NFC reader and sure enough…
…it worked! My payment went right through.

Just as the directions say I did not have to have my display on, although the phone did wake once initiated. I also used Windows Hello to login although I am not sure if that is because Wallet requires it for security or if my phone had just enabled it for the Lock screen. Clearly, more testing is needed so I'll be eating fast food all weekend for science.
Microsoft has announced that their mobile payments will utilize Host Card Emulation(HCE), making this a non-proprietary solution and one that piggybacks off current NFC payment systems already in place. As a result, Tap to Pay on Windows 10 Mobile should find ubiquitous access to NFC payment systems already installed. What that means in English is this should work at almost all places that currently accept NFC payments and it will not require a special Microsoft-Vendor-Bank deal.

Immediately following the transaction, I received a push notification confirming the purchase, which was a nice touch.
Overall, the experience was flawless, and even I was surprised that not only it worked at this early stage, but it was flawless too.

Only the US at launch?
Microsoft has not publicly commented about its Tap to Pay and Wallet plans, but my guess is that it will roll out starting in the United States first. The US-focused store listings for the loyalty cards implies this as a US feature and once we finally enabled it on a localized UK phone, there were no banking or credit card options.

However, we should heed caution until Microsoft announces this service for Windows 10 Mobile. They could very well launch it in numerous markets either initially, or in waves. For now, we will just have to wait and see.

Finally, since Microsoft has not announced this service we also do not have a timeframe for a launch. Seeing as the service is already working on Windows 10 Mobile Redstone builds (Insider Fast Ring), there is a good chance it will be time with the Anniversary Update, which is expected at the end of July.
