The biometric authentication on consumer devices has become mainstream with the arrival of the iPhone 5s and its fingerprint sensor called “TouchID”. Manufacturers of Android smartphones like Samsung, LG were quick to follow, but Google did not start supporting fingerprint scanners last year with Android 6.0 Marshmallow.


Well, better late than never and thanks to the native implementation of Android, application developers too have begun to implement in their applications, which has made sure that fingerprint scanners are Indeed useful and not just a gadget. So if you bought a brand new Android smartphone that packs into a fingerprint reader, here are 6 ways it can come handy:

  1. Shopping Authenticate on Google Play Store

Authenticating app & games shopping on Google Play Store is important because otherwise, even a child playing a game on your device can go ahead and accidentally buy something. Previously, Play Store would allow you to confirm your purchases by entering the password for your Google Account.


However, it can be a long process and that is when a fingerprint scanner is very convenient. You can simply go to the Reading Settings store and activate “fingerprint authentication” and the next time you make a purchase, you can easily authenticate it with your fingerprint.

  1. Order with Android Pay

We are all aware of Android Pay the Google platform that allows you to use your credit card to make purchases without ever taking your wallet. Well, what makes it even easier is the integration of the fingerprint scanner. Instead of checking a payment with a PIN or password, you can simply use your fingerprint to quickly check for a payment.


So basically if you buy something in a store you can just tap your phone with the terminal and Android Pay will be pop-up for payment verification and then you can use your fingerprint to confirm it.

  1. Lock applications with your fingerprint


Using a fingerprint to unlock a blocked application on Android should be more efficient than entering a PIN or pattern and while Android does not allow you to lock/unlock individual applications via the fingerprint sensor you can do it via a third-party application.

  1. Password Managers

Password Managers are applications that allow you to store all your passwords in a single, secure location. Although these applications are generally very secure, fingerprint authentication in Android makes things even better.


Having a fingerprint lock should make sure that no one simply goes ahead and sees your passwords. Additionally, these applications allow you to connect anywhere using your fingerprint sensor, whether it be other Chrome applications or Web pages.

  1. Banking

Banking applications are something that we use a lot to make our payments and transactions but entering our password every time to get into the application can be a problem. Also, if our phone is stolen and the thief manages to penetrate inside the application. It’s scary, is not it? Well, no more, thanks to the fingerprint scanners.


Most banking applications have begun to incorporate the fingerprint sensor so that you can perform transactions with a tap at the sensor. All banking applications still support, but with most new Android smartphones with a fingerprint scanner, they should do so soon.

 Intelligent Home Integration

Home automation is rapidly gaining prominence and there are the plethora of smart home appliances and home security devices that work through an Android application. So, would not it be great if it worked with the fingerprint scanner?


While we are still seeing applications for smart home supporting fingerprint scanners, we really hope to see them implemented quickly. Having fingerprint authentication on smart home control applications should make things windier but secure.

What is your favorite use of the fingerprint scanner on Android?

If you have used a new Android smartphone with a fingerprint scanner, chances are, you might only use it to lock/unlock your smartphone.


Well, there’s definitely a lot more you can do with it and we can expect the uses to grow even more, as fingerprint smartphone packing scanner become a standard. So, what is your favorite use case of the fingerprint scanner on Android?
