outbreak fingerprint sensors in mobile phones was in the mid 2010's. At first, the manufacturers placed them on the front panel below the display, there, where the touch of a button. It's a simple and logical arrangement gave the ability to quickly unlock, provided convenient access position of the finger and a smartphone in the hand. But over time, this design ceased to be successful – the users wanted more screen space. The war started with the framework. Dactyloscopy, which we knew had to leave the usual place of residence.

Being on the side faces of the smartphone, they provide fast and easy unlocking your device you just need to take in hand, and the finger itself will fall on the sensor.
But all these facilities can be assessed only right-handed users. Left-handers, especially at the tail tabletag, to control the scanner on the right side is not so easy.
Except that the square end of the scanner is small, so it is able to learn only a small part of the finger surface and only if the user with pinpoint accuracy will make it to the sensor.
