Fingerprint sensors have really started to pick up steam in 2015, with more and more OEMs using them in their devices. Sure we had seen devices before with fingerprint sensors like the HTC One Max, Huawei Ascend Mate 7, and the Samsung Galaxy S5. But in 2015, we're seeing many more coming, as well as Google bringing in support for them in Android M.
I've spent the past few weeks with the Meizu MX5, and while the fingerprint sensor has been very good, fast and accurate, it left me wanting it to do more than just unlock the device and log me into my Flyme account. Also the fact that you can only use one finger, felt like a let down. I've also spent the last few days with the iPhone 6 (I know, I know, but gotta see what the competition is doing), and surprisingly Apple's Touch ID is really, really good. It's used for many things compared to the Meizu MX5, and even the Samsung Galaxy S6.
I might be alone here, but what I want from a fingerprint sensor is to be able to login to all my apps with my fingerprint. I'm not sure about all of you, but I have so many logins for so many apps and websites that it's tough to keep up. But if I could login to each and every one of them using my fingerprint it'd be much nicer. Sure unlocking your phone with your fingerprint is pretty cool, but if you're paying extra just for that, it just doesn't seem worth it.
What we do know is that Google has support for fingerprint sensors in Android M, we don't know how far that's going to go just yet though. We do know that it'll work for Android Pay, so when you are out shopping and pull out your phone to pay for your purchase, you are able to just use your fingerprint instead of a PIN number to authorize the purchase. Hopefully Google will have support for using Google Play, and making it easy for app developers to allow users to associate a fingerprint with their account in an app. For example, using a fingerprint to sign into Twitter, would be spectacular.
