Users of devices running the latest version of Android, Marshmallow, are now able to authenticate purchases made on the Google Play Store using the fingerprint scanners on their devices.
Though some Android devices from HTC, Samsung and Huawei have had fingerprint sensors in the last two years, it was not until the arrival of Android 6.0 Marshmallow that native support for fingerprint scanners was added. As a result, Google is expanding the use case of the fingerprint sensors on Android devices besides support for mobile payments (Android Pay).
At the moment, only two devices, the Nexus 6P and the Nexus 5X, have Android Marshmallow even though the other devices, mostly high end models, from the likes of LG, Motorola, HTC and Samsung are expected to get it soon.
