With Android 6.0 slowly but surely rolling out to compatible devices, one of the highlighted features of the new software update is the standard fingerprint reading across the Android system. By implementing fingerprint scanning into the Android system, Google will use it not only for unlocking your device, but using your fingerprint to confirm Play Store purchases.
For devices with Android 6.0, Google now gives you the option in the Play Store to confirm purchases with your fingerprint, but you’ll have to activate this option first. By default, fingerprint authorization is off. You can activate the feature by going into the Play Store settings under ‘User Control’, where you will then have to enter your Google password.
Many more apps will begin to implement the option of using your fingerprint for authorization purposes, such as mobile payments and simply using your fingerprint as a password for some apps.
