a fingerprint Scanner on a smartphone: pros and cons

Modern smartphones increasingly have at their disposal a fingerprint sensor. It aims to provide sensitive data contained on the device. But is it a useful fingerprint scanner on a smartphone as it seems? Let's try to figure it out.

At the ignorant person the impression that buying a handset with fingerprint sensor will cause only positive emotions. But practice shows that this is not always the case. In today's article we will explain why some people don't use the fingerprint scanner — why he seems useless. But it is impossible not to notice that the sensor has a number of advantages — they also talk.

the Essence of sensor

The words "fingerprint sensor" we mean a small scanner which detects the pattern on the skin applied to it the finger. Previously, such a sensor was too expensive therefore it was applied only to banks, but also some government and military agencies. And the size of the scanner was too great, which none of the smartphone manufacturers did not even think about its implementation. But technology is evolving around 2015, this element has started to be used in all flagship. Moreover, the cost of the fingerprint reader fell sharply, which he began to appear, and not the most expensive devices.

In the first place the fingerprint sensor is designed to protect your smartphone from prying eyes. If the other person will take your device in hand, next lock screen it can't. Imprint any of his fingers will be different, therefore to unlock the phone, he can not. In theory, the scanner can be fooled. But it's such a time-consuming process that can deal with it only the security services, and even then not always.

with iPhone 5S began mass adoption of fingerprint sensors

Also, this sensor is used in security payments. If before confirmation the payment was entered the password, now it to remember is not necessary — enough to put finger on the scanner. It is very convenient! In the same Play Market people do not include proof of payment with a password, as they simply forget. As a result, then they are faced with the fact that their children sometimes completely unconsciously make a lot of purchases of paid apps and games. Using the fingerprint scanner this problem can be solved at the root!

Main advantages

Let's talk about the good smartphones with fingerprint scanner.

  • As mentioned above, your child won't unknowingly buy something in Google Play, as he might need to apply your finger to the sensor. Of course, a clever child can bypass the problem by using your hand when you sleep. But children at this age it is better to provide their own tablet or smartphone to the account which is not tied to Bank card.
  • unlock with fingerprint is greatly reduced. Surprisingly, some fingerprint sensors are triggered very quickly. Much faster than if you held your finger on the screen.
  • Stranger will not be able to access the information contained in the memory of the smartphone. But if you use encryption, the attacker will be unavailable and memory card, even if it is it would be inserted into a card reader of your computer.
  • In Android 6.0 support for the fingerprint sensor embedded on the operating system level. This means that you can use a fingerprint in various application. For example, this can be done in the browser, autorizovany on the sites without entering username and password. Again, this is the perfect option for those people who do not want to keep in mind many different passwords, a fingerprint supersedes them all.

Disadvantages sensor

Of course, as with any new technology, the fingerprint scanner has a number of drawbacks.

  • In a cheap budget smartphone embedded sensors belonging to the first generations of this technology. They process the information long enough — sometimes up to one or even one and a half seconds. There are times when fingerprint is not recognized the first time. If your device has such a sensor, you'd be bored to use to unlock it. After a few days you will prefer other methods, as they allow you to spend less on the process time.
  • The fingerprint scanner is not needed the tablet if it is used by several family members. Of course, modern sensors allow you to store the fingerprints of several fingers. But even with this capability, problems can arise when a device wants to take advantage of a child. Each unlock will require the latch finger to the scanner. And not the fact that young boys are consistently recognized. If the device is designed for the entire family, in most cases, the fingerprint scanner will turn off, as it brings additional complexity.
  • Is that your smartphone will not be able to take advantage of another person are not only advantages. If something happens, bystanders, medical brigade or police will not be able to call your family members, as they simply will not be able to unlock your phone. However, of all the trouble to think no one wants.
  • In smartphones from Apple Inc. all fingerprints are stored in encrypted form. But on devices with Android until the situation was much worse. All these data were stored in local memory in an unprotected form. Some hackers with a strong desire can get access to this information. Luckily, the new smartphones this problem is solved.


Some people the disadvantages indicated above may seem far-fetched. But in fact it is not. While no one would argue with the fact that advantages of smartphones with a fingerprint scanner more. Not for nothing Google has implemented in its operating system support fingerprint sensor at the deepest level. It is not excluded that in the future they will be equipped with even the most cheap smartphones.

in the meantime, be sure to read reviews on the machine that you wish to purchase. If it has an old sensor, users will certainly notice a fact long unlocking using the fingerprint. In this case it is better to consider some other model, a little more modern.
