fingerprint scanner Many modern smartphones have fingerprint scanners, but now new technologies allow integrating the sensor into the display and abandoning the special button with the sensor. How it works is described in the article.
In smartphones, where the fingerprint sensor is built into the display, when unlocking the screen tells where to place your finger. In this place, a sign in the form of a fingerprint itself is usually highlighted.
At the moment, the technology does not yet allow you to scan the fingerprint anywhere on the display. However, it is possible that soon the entire display area will be equipped with such scanners. Given that the technology of “sensor in the screen” appeared recently, we can expect that it will improve in subsequent generations of devices.
