Fingerprint scanner on a smartphone: pros and cons

Modern smartphones are increasingly equipped with a fingerprint sensor. It aims to secure sensitive data contained on the device. But is a fingerprint scanner on a smartphone as useful as it seems? Let's try to find out.

An ignorant person gets the impression that buying a device with a fingerprint sensor will cause him only positive emotions. But practice shows that this is not always the case. In today's article, we'll explain why some people don't use a fingerprint scanner - why they find it useless. But it is impossible not to notice that the sensor has a number of advantages - we will also talk about them.

The essence of the sensor

Under the words "fingerprint sensor" we mean a small scanner that recognizes the pattern on the skin of the finger applied to it. Previously, such a sensor was too expensive, and therefore it was used only in banks, as well as in some government and military institutions. And the dimensions of the scanner were too large, because of which none of the smartphone manufacturers even thought about its implementation. But technologies are developing - since about 2015, all flagships began to be equipped with this element. Moreover, the cost of a fingerprint scanner has dropped dramatically, which is why it began to appear in not the most expensive devices.

First of all, the fingerprint sensor is designed to protect the contents of the smartphone from prying eyes. If another person picks up your device, then they will not be able to go beyond the lock screen. The fingerprint of any of his fingers will be different, and therefore he will not be able to unlock the device. In theory, the scanner can be fooled. But this is such a laborious process that only special services can cope with it, and even then not always.

Also, such a sensor is used to secure payments. If earlier a password was entered to confirm the payment, now you do not need to remember it - just put your finger on the scanner. It is very comfortable! In the same Play Market, people do not include a password payment confirmation, as they simply forget it. As a result, then they are faced with the fact that their children sometimes completely unconsciously make many purchases of paid applications and games. Using the fingerprint scanner, such a problem is solved in the root!

Basic advantages

Let's find out what the smartphones with the fingerprint scanner are good.

  • As already mentioned above, your child will not be able to buy something unconsciously to buy in Google Play, because for this It will take to attach your finger to the sensor. Of course, a smart child will bypass the problem when you use your hand when you sleep. But at such age it is better to provide their own tablet or smartphone, whose account will not be tied by a bank card.
  • Unlocking time with fingerprint is significantly reduced. Surprisingly, some dactyloscopic sensors work very quickly. Much faster than if you were spent with your finger across the screen.
  • Strying person will not be able to access the information contained in the memory of the smartphone. And if you use the encryption function, the attacker will be unavailable and the memory card, even if it inserts it into the card reader.
  • In Android 6.0, support for the dactyloscopic sensor is embedded at the level of the operating system. This means that you can use a fingerprint in a variety of applications. For example, it can be done in the browser, authorized on sites without entering a login and password. Again, this is the perfect option for those people who do not want to keep many different passwords in memory - fingerprint replaces them all.

Disadvantages of the sensor

Of course, like any new technology, fingerprint scanner It has a number of shortcomings.

  • In low-cost smartphones, budget sensors are embedded, belonging to the first generations of this technology. They process information sufficiently long - sometimes up to one or even one and a half seconds. There are cases when the imprint is not recognized from the first time. If your device is at the disposal just such a sensor, then you will quickly get used to use it for unlocking it. Already in a few days you will prefer other ways, as they allow less time to spend the process.
  • The fingerprint scanner does not need a tablet if they use several family members. Of course, modern sensors allow you to store fingerprints of several fingers. But even with this possibility, problems can arise when a child wants to use the device. Each unlock will require placing your finger on the scanner. And it’s not a fact that little toddler boys will be consistently recognized. If the device is intended for the whole family, then in most cases the fingerprint scanner will be disabled, as it introduces additional complications.
  • Not only advantages lie in the fact that another person cannot use your smartphone. If something happens to you, then people who happen to be nearby, the medical team or the police will not be able to call your relatives because they simply will not be able to unlock your phone. However, no one wants to think about all sorts of troubles.
  • Apple smartphones store all fingerprints in encrypted form. But on devices with Android, until some time, the situation was much worse. All these data were stored in local memory, in an unprotected form. Some hackers, with a strong desire, can gain access to this information. Fortunately, in new smartphones this problem is solved.

Summing up

Some people may find the above disadvantages far-fetched. But actually it is not. Although no one will argue with the fact that smartphones with a fingerprint scanner have more advantages. It’s not for nothing that Google has implemented fingerprint sensor support at the deepest level into its operating system. It is possible that even the most cheap smartphones will be equipped with it in the future.

In the meantime, be sure to read the reviews for the device you want to purchase. If it is equipped with an old sensor, then users will definitely note the fact of a long unlock with a fingerprint. In this case, it is better to consider some other model, a little more modern.
