PSA: You can now pay for Play Store purchases using your fingerprint
If your lucky enough to own a smartphone that’s running Marshmallow and has a fingerprint sensor on board, we have some pretty great news for you. Starting today, you can pay for your Play Store purchases by simply placing your configured finger on the device’s biometric scanner.
Seeing as the functionality is only available on a handful of devices at present, it’s not enabled by default — so you will have to activate it manually. Doing so couldn’t be any easier, though. All you have to do is head into the Play Store’s settings menu, tap User Controls then check the box for Fingerprint Authentication.
