At Mobile World Congress Shanghai, Qualcomm announced the release of high-tech fingerprint sensors which can read your fingerprints in almost any conditions. More precisely, the sensors will work even if you place your finger over the display, glass, or metal.
The new Qualcomm Fingerprint Sensors are more modern and can support more kinds of form factors. Now it will be easier for you to authenticate on your phone and, at the same time, benefit from advanced security features. Also, the sensors can work through slightly thicker layers of glass or metal.
The new fingerprint sensors are modern and bring improvements from the previous generation
In fact, the series includes three different types of sensors. One sensor works for glass surfaces, another is for display, while the third one works for metallic surfaces. The display sensor is the first to become available on the market. It will be an ultrasonic scanner, being able to scan your fingerprint even through an OLED display.
The glass and metal scanners will come with improvements. They will be able to scan through surfaces of 800 micrometers of glass and, respectively, 650 micrometers of aluminum. This is quite a big progress from the previous scanners, which supported only a thickness of 400 micrometers of aluminum or glass.
What devices are they compatible with?
These fingerprint sensors are designed for the new line of Qualcomm Snapdragon processors, but they might be compatible with other chips as well. The first processors which will make use of the sensors are the recently announced Snapdragon 630 and 660. When it comes to the operating systems, they will work on both current and future Android versions.
Samsung reported it faced some difficulties in including this kind of technology for Galaxy S8, S8 Plus, as well as Galaxy Note 8. When it comes to Apple, the company was still undecided if it should feature the upcoming iPhone 8 with such a fingerprint sensor.
