With this feature now native to Android, applications and services will be able to utilize a user’s fingerprint for added security, such as when a user makes a purchase on or through the device.
For example, if you are browsing Google Play and decide to make a purchase, instead of entering in your password, you can simply use your finger. In addition, when using Android Pay at a supported retailer, you can use your finger to complete the transaction, without the need to enter any passcode.
Of course, your hardware will need to feature a fingerprint scanner in the first place, and as of right now, not many flagship devices do. With this added feature, you can expect more OEMs to dive into offering fingerprint readers on their devices.
Excited to use your fingers more when purchasing goods?
