Fingerprint sensors are very popular means of biometric recognition of users on mobile phones and laptops.
However, with the advent of the trend of mobile phones with the screen extending from one board to the other, there is little or no room for the front of the camera to accommodate such sensors, so some, like Epla, have decided to leave the technology.
However, other sensors are located at the back or side of the device or are exploring the possibility of their invisible integration in the screens themselves.
This latest technology is particularly interesting, especially if it could in the future be combined with the discovery of South Korean scientists recently published in Nature.
They designed a fingerprint reader that is flexible and transparent, and in addition to being able to read the papillary lines of the skin, is able to simultaneously record the pressure on it as well as the temperature of the fingers, Bug.hr writes.
With these new features, sensors become much safer because they are more difficult to "scam" through various copy methods.
The technology has been tested and, as its creators say, the quality of reading and fingerprint resolution meets the standards set by the FBI.
Also in the description of a new type of sensor, it is remarkable its excellent resistance to bending and the possibility of a discrete installation inside and / or under the roof. screen of a mobile phone.
