The addition of a fingerprint application programming interface (API) to Android phones using the Android 6.0 Marshmallow OS makes purchasing at Google Play easier.
The fingerprint authentication is one of the features found in the API that quickly authorizes purchases with just the fingerprint. The feature means its function goes beyond securely unlocking a device or the phone's lock screen, reports TechTimes.
Currently, only owners of the new Nexus 6P and Nexus 5X support the fingerprint authentication which Android Police initially reported after the teardown of a v5.9 client in early September.
But because the fingerprint reader option is disabled by default, owners of these two smartphones would need to activate that feature in the Google Play store to authenticate payment with just their fingerprint.
There are two ways to activate that feature. First, is to open the Google Play app and go to Settings > User Controls. Second, is to tick on or off the box on Fingerprint Authentication under User Controls to activate or deactivate that feature for buying. For those using the second option, check the Fingerprint Authentication box then enter your Google password once Play Store prompts.
Future gadgets that uses Android 6.0 Marshmallow OS would have the Fingerprint Authentication function and a fingerprint reader which owners could use to buy items at Play Store.
Besides that feature, Android 6.0 Marshmallow also gives users more control over apps and how the phone functions. Other improvements in the latest OS include battery backup and support of links from apps, reports Nycity.today.
