Google spilled more details about Android Pay, its answer to Apple's and Samsung's respective mobile payments services, during Google I/O this week, announcing that it will debut alongside Android M in the third quarter.
While Google has yet to cough on international release date details, with the service set to arrive in the US in just a few months' time, yet more competition will soon be added to the steadily-growing mobile payments market.
We've rounded up five things you need to know about Android Pay.
It will work on any NFC-compatible device
Android Pay will work with any Android smartphone that comes with NFC baked in, and Google boasts that seven out of 10 Android devices will be ready for Pay when it launches later this year.
You'll be able to use it in-app
Getting one-up on Apple Pay, Google has announced that Android smartphone users will be able to use its mobile payments service to purchase goods in-app.
The firm said: "The days of entering your credit card and shipping address each time you make a purchase online will be a thing of the past. Just select 'Buy with Android Pay' and leave the rest to us; checkout is as fast as a tap."
At launch, Dominoes, Etsy, Groupon and Uber will be among the first to support Android Pay in their apps.
700,000 US stores will support it at launch
Google announced during its I/O keynote that, when it launches later this year, Android Pay will be supported at 700,000 US retailers from the get-go, way more than the 220,000 that supported Apple Pay at launch.
This is because shops don't need to update their existing kit, and can take payments using already-installed NFC contactless terminals
These 700,000 stores include Best Buy, Gamestop, Subway, McDonalds and Whole Foods. The payment service has already received support from key payments service providers too, including MasterCard and Visa.
It will work with devices running Android 4.4 Kitkat
Although Android Pay will make its debut alongside Android M in the third quarter, Google surprised many during its I/O keynote with the news that the payments service will work on smartphones running Android 4.4 KitKat and above.
It will support Android M's native fingerprint authentication
During its I/O keynote on Thursday, Google announced that Android M will be the first version of its mobile operating system to come with native fingerprint authentication.
As well as letting users authorize Google Play purchases and developers' to bake fingerprint support into their apps, this feature will also allow users to use their digits to unlock Android Pay, in a similar way to how Apple Pay works on the iPhone.
