Fingerprint technology in smartphones from the past to the present

The fingerprint reader on smartphones is one of the most widely used security measures in the world. A fingerprint reader has become standard even on entry-level phones. Well, let’s have a look at the changes in this fingerprint reader in our life from past to present.

Technology is advancing at such a rapid rate that it is getting more and more difficult day by day to keep up with new or upcoming technologies. However, we can adapt more quickly to changes in smartphones. One such big change is the fingerprint reading technology.

Fingerprint engraving tools built into the home button

Although two Chinese smartphone manufacturers, whose names were not prominent before, used fingerprint readers on smartphones, the Apple iPhone 5S is the first phone to make a splash. At the same time, the presence of the first 64-bit architecture processor was the highlight of the device. People started using the middle button, which was used from previous generations, to use fingerprints this time around. While entering a password or PIN on the screen is a waste of time, entering via a fingerprint scan is a safer and easier option. Apple has continued to use fingerprint reader technology on many models (6.6s, SE, 7,7 Plus, 8 8 Plus, SE 2020). In fact, fingerprint readers are so adopted that Apple updated the fingerprint reader on the iPhone 6S model and put in a faster one. Not only that, he has used it on some iPad models and is still using it.

Fingerprint readers on the back cover

On the Android side, fingerprint readers started being used more after Apple. However, it is not built into a button at the bottom of the screen as in Apple, but is placed on the top of the back cover. Since Android smartphones offer a much better screen-to-body ratio, there was no room for a fingerprint reader at the front. Although this reader, tucked away by necessity, was offered as a convenience by some consumers, it was deemed unusable for others because it was in such a hard-to-reach location. In addition, due to the large size of phones, it became difficult to control the phone with one hand, and it became difficult to access the fingerprint directly. Huawei and Samsung are among the brands that use the fingerprint readers on the back the most.

Fingerprint readers built into the power button

With the growth of smartphones, manufacturers have been able to integrate fingerprint digging tools, which were difficult to reach with one finger, into the power button with a clever movement. In this way, it was possible to use the fingerprint readers in a more comfortable carrying position. In addition, with the development of technology, fingerprint engraving speeds have also improved at the same rate, and fingerprint readers are available for less than one second. The power switches, which are usually located to the right of the case, can also be a problem for some people. We can say that the reason for this is that when consumers only want to read notifications from the lock screen, when they press the power button with their fingers, where they present their fingerprint, the lock is unlocked instantly. However, we can say that it is much more practical and comfortable than the button at the bottom of the screen or the button on the back.

Fingerprint readers are placed under the screen

If we look at the most advanced and latest security systems, we have said that fingerprint readers are the most widely used. We can say that the reason for this is that each person’s fingerprint is unique and unique. The most common use of fingerprints on smartphones is the systems now embedded under the screen. The inventor of this system is Vivo. The smartphone, which was shown at an exhibition in 2018, attracted a lot of attention. Since then, the most widely used fingerprint reading system has been the under-display technology and brands are still developing on it. Thanks to the light sent to your finger at the bottom of the screen, these readers, which read your fingerprint, have evolved over time to become ultrasonic readers. Users loved it because it’s more accurate, more accurate and safer with 3D scanning with more printing. However, the fact that it is a technology only used with AMOLED screens makes it more expensive. On the other hand, smartphones using IPS LCD screens cannot support fingerprint readers located under the screen due to the thickness of the panel. On these phones, the power button, which offers a physically faster option, or the readers on the back are preferred.
