There are a handful of phones out there today that have a fingerprint scanner on it allowing users to unlock the device, make payments at a register, or make a payment for an app from an app store with a simple swipe of your finger. All those phones have the scanner on the front or side of the device, but none have a scanner used by the camera. An Android app called “App Lock Finger Print” is a fingerprint scanner that uses the camera to unlock apps of your choosing.
Setup is super easy, but can take a bit of time. Why you may ask? Well, when applying a fingerprint, the camera has to focus on which finger your choose on your left or right hand. It was a little bit of a struggle as I kept moving my finger slowly forward and backward so the camera can focus on it. The app states the ideal range is 4-6″ (7-10cm) from the camera to scan your finger, but that didn’t always work. During the process of setting up your fingerprint, it shows an outline where your finger needs to go. When scanning, it took 7 times for the app to learn my fingerprint. Seriously, it was a struggle. I was able to get 8 out of 10 good scans.
Once done with that, you can start locking applications of your choosing. When you pick that app you’ll be prompt to either choose Finger Print Lock, Pattern Lock, or Number Lock. Next, head to the app drawer or home screen said locked app is and tap on it. The same screen that came up when scanning your finger will show up. Simply get your finger in focus and the app will unlock.
I locked the Amazon app as a test and it worked pretty well. I had to unlock it twice as my password was needed the first time. This may not be the same for everyone.
It’s a great concept, but would you ever use this fingerprint scanner app to unlock certain apps? Let us know by leaving your comment below, or on Google+, Facebook, or Twitter.Source: PhoneArena Get App Lock Finger Print from Google Play
