The unlock mechanisms like PIN, patterns and password on Smartphones are behind when fingerprint unlock arrives, which is a personal system, offering more security, easy access and fast for the user.


Security is a key element of the “smart” mobile phone, because this equipment is no longer just a communication tool to become the technological device with which a person interacts and even be an electronic wallet.


To keep the data of the telephone safe the usual thing is the use of alphanumeric keys, patterns drawings in the screen, or the registry of a fingerprint.


The first is safe, but it is the most annoying to enter, because the user wants to unlock the phone quickly, something impossible if you must write “Fulano3*”.


In contrast, the fingerprint grows in acceptance by the improvement in biometric sensors, which now allow to slide the finger on them without having to do it with enough precision.


On Moto (formerly Motorola), the mobile division of Lenovo, they put in numbers these times: on average, a person unlocks their cell phone 80 times per day, and typing the key takes 3 seconds. This translates into 24 hours a year, ie 3 full working days only to unlock the phone.




Denise Sommerfeld, director of device marketing, “unlike other mechanisms such as patterns, PIN or password, the fingerprint is totally personal, so it offers greater security , Absolute personalization and, at the same time, a more practical alternative for the user, since access is easier and faster.


Jean del Pino, mobile marketing manager for Samsung Argentina, told that the fingerprint “is the safest and most practical way to block and protect the phone” and agreed with his colleague Huawei that “in terms of user comfort , Is the easiest and fastest to use, avoid having to remember passwords “.


Martín Errante, product manager of Lenovo MBG, recalled to that the different methods to unlock the “smartphone” were changing with the passage of time.


“The years taught us that both the pattern, the numeric PIN and the password can be easily detected by third parties if we do not exercise care when entering them,” said the executive.


With this technology “we avoid having to type and remember multiple passwords, because simply by touching the fingerprint reader, our devices are instantly unlocked,” said the Moto executive.


“The user does not run the risk of forgetting the key and also avoids a step to enter the equipment, because pressing the button recognizes the fingerprint and enters the system directly without typing,” said iProfesional from the local office of Sony.


Available Models


Within the Huawei product portfolio available in Argentina, the smartphones that include the possibility of access through fingerprints are Mate 8 and G8. In both cases, it is available in the back as in all Chinese brand equipment.


The G8 offers Fingerprint 2-generation algorithms (faster), 360 ° reading (more comfortable), 94% successful recognition in 0.5 seconds (more accurate) and independent RPM (more secure) level chipset.


In Mate 8 (in the image below), the circular fingerprint sensor has an improved concave depth, increasing the effective identification area, doubling the recognition rate and reducing the error rate by half.

Sommerfeld said that between the launches planned by Huawei this year in Argentina are included two models incorporating the option of fingerprint system: the P9 Lite (mid-range high) and the P9 (high-end). In the latter case it is possible to record up to five different fingerprints.


Samsung has available in Argentina this system in its Galaxy S7 (in the image below), as well as the previous versions from the S5 onwards, and in the Galaxy A5. In these models, the scanner is integrated in the “Home” button to simplify access to the smartphone. This year the South Korean brand plans to launch in Argentina the Galaxy A9 that will have this system.

The Moto teams that have this technology are the Moto G4 Plus and the Moto Z Play. In the first model, the fingerprint reader is located at the front, in the center of the bottom, which with a simple touch is enough to activate and unlock the phone. You can even use it to authorize purchases in the Google Play Store and other permitted apps.

It is very likely that we will add more members of the Moto family, but we can not confirm anything about future launches, said Errante.


In the case of Sony, the Xperia X (in the picture below) is the only “smartphone” in Argentina that has the possibility of access through the Finger Print Sensor, located on the right side of the phone, power button.

From the Japanese brand assured  that “it is much easier and intuitive” for the user “to place the sensor on the side of the equipment due to the natural hand grip.”


Question of ranges


Is the fingerprint so far an exclusive system for high end models? For Sommerfeld the answer is negative, and announced in this respect that in 2017 Huawei will give Argentine consumers the possibility of accessing a “smartphone” mid-range that also includes the fingerprint unlock system such as the P9 Lite.


Del Pino recalled that Samsung has high-end models with this system as is the case of Galaxy A5, and the Galaxy J and J5 Prime were the first mid-range Galaxy smartphones with a fingerprint sensor.


Errante noted that in 2016 Lenovo launched the Moto G4 Plus that offers unlocking via fingerprint as technological innovation in the mid-range.

On the other hand, from Sony they admitted that “for the moment this development is focused on our teams flagship” as the Xperia X.
