The ultrasonic fingerprint sensor used in the Samsung S Series, although not defective, has many advantages over optical sensors.

Two days ago, Samsung unveiled its latest flagship Galaxy S10 series. These galaxy phones, along with all the extraordinary features, have also integrated the world's first ultrasonic fingerprint sensor. Previously, other companies like Huawei and VanPlas also used a fingerprint sensor below the display, but the sensor used in their products was optic or optical. The new sensor has many advantages over the previous model, which we will continue to discuss.

Most importantly, according to Qualcomm, the company's 3D Sonic sensor is safer than existing two-dimensional optical sensors. The new technology uses sound waves to build a 3D model of the protuberances and dentures on the finger and at the same time can detect the flow of blood. This prevents any system abuse and deception by artificial fingers. Another advantage of the system's responsiveness is that your finger is wet, dirty or wet.

It's said that optical scanners, since they produce glare for fingerprint detection, are overlapped by the shadowing of OLED displays, but 3D Sonic sensors do not have this problem.

The other advantage is the new low-sensitivity sensor, which is only 0.2mm thick, making it an excellent choice for use on slim phones. In addition, since ultrasound sensors are able to detect blood flow, they can also be used simultaneously to calculate heart rate, BMI and blood glucose, in order to store space in the design of the phone for other components.



Another advantage of the ultrasonic sensor is its much lower battery consumption. In addition, ultrasound does not interfere with Stylus.

Qualcomm is not alone in making and supplying this chip, and has done this with the support of FIDO. The Fido Union has confirmed this product as part of its Biometrics Licensing Program.

The Galaxy S-10 has been confirmed as the first device by the new union to ensure that the new solution is safe, as with any native technology, this new solution is no problem; unfortunately, if your phone is of this type The sensor will not be able to use any kind of screen saver. Therefore, Galaxy S10 and S10 Plus buyers should take this into account.
