Fingerprint scanner is not a new feature. Almost every smartphones nowadays sports this feature for the security. However, smartphone fingerprint scanner is not a good security method. Do you know why? Just take a look at our post below!

Smartphone fingerprint scanner: is it an ultimate security method?

Firstly, as its name- fingerprint scanner, your fingerprint is the only way to enter your phone. It’s just like a key to a house. And this house can be broken into thanks to this key. You can leave your key on any object: the screen of your smartphone, the drinking glass or on any smooth surfaces. And anyone can scan your fingerprint by using the camera having high resolution. And you can find this kind of camera on almost every smartphone today.

Secondly, the fingerprint sensor can be fooled. Like I say above, the fingerprint is easy to copy. All you need is a high-quality photo of the fingerprint, a fastener, and a high-resolution printer. There are some advanced sensors just accept the heat or the beat of the fingerprint. However, even this high-end sensor is not very difficult to pass. A fingerprint pattern and a skin colored material are what you need. And the sensor can easily be tricked.

The third reason is that it’s easy to force you to unlock your phone with a fingerprint security. Anyone who wants to unlock your smartphone can make you do it by force. They can grab your hand and put your finger on the sensor. It’s even much easier when you’re sleeping or unconscious. Fourthly, many smartphone companies don’t know how to equip smartphone fingerprint scanner properly. Some even just do it to attract users. HTC One Max is an example. The fingerprint sensor on this phone is inconvenient and hard to use.

Smartphone fingerprint scanner: not as safe as you think

Here we come to the fifth and also the last reason. This feature sometimes works, sometimes it doesn’t. It’s reported that the sensor on iPhone 5S is not always working. There are some trouble. There are various factors affecting this sensor like dirt, the moisture on the finger, software problem or the glass covering the sensor. So, you shouldn’t rely too much on smartphone fingerprint scanner. It’s not as secured as you think.
