Qualcomm’s New 3D Sonic Max Sensor Is Massive


Qualcomm seems to take a different approach from the rest of the phone industry last year when the company announced a 3 D Sonic-in display fingerprint sensor. The innovation refers to the fact that instead of relying on the optical image of fingers for authentication, the 3D sonic system makes use of ultrasound to attain the impression of the surface texture of the prints.

The article will include the fact that Qualcomm’s new 3D Sonic Max sensor is massive and has excellent functionality in comparison to the previous model announced by the company.

The method includes the couple of advantage that usually makes use of scanner with the wet finger as well as adequate security in comparison to the optical sensors available in the market. In the recent phase of time, the company is announcing the 3D sonic Max Fingerprint sensor that shows that it is the largest sensor and 17 times more abundant in comparison to the predecessor.

It will help to deliver great advantages; however, the most significant feature among the other refers to the enhanced security, which has been considered. It has been seen that both optical and ultrasound fingerprint has some significant drawbacks. The relatively small size made them far less secure than the larger ones. The larger sensors seem to acquire detailed information and attempt to find an additional signal for the identification and inherently more stringent. The 3D Sonic Max scanner appears to measure the 20mm*30mm for the 600 square millimeter area and seems to lessen down the chances of fooling such a system to a significant effect.

The company has been allowing the dual fingerprint authentication that has been available with the large surface area indicating the fact that the system requires two unique prints at the same point. Also, it can be used for the condition that needs high security, such as accessing the bank application or sensitive information of the company.

  • The larger scanner seems to add a few other benefits to the company and allow the user to register the fingerprint on the phone just by tapping once, instead of repeatedly for about 16 to 20 times. With such a large target area, too, you can more easily sign into your device instead of blindly jabbing your finger at a spot where you think the scanner is.
  • Most in-display areas seem to be quite small in comparison to the actual thumb due to which, when an individual looks to unlock the Smartphone, there has been needed to identify where the sensor has been located. It has been seen that the sensor tends to be millimeters wide by being 2-3 mm, which indicates the likelihood of the positive unlocking is down to the quality of the sensor along with the software. Some mobile phone that has always on-display gets around by providing the fingerprint to display where the individual needs to press. However, it even gets displayed after you have touched the display once.

Qualcomm built its reader on thin-film-transistor, which seems to be identical to the material that has been used in LCD to keep the cost minimum and seems to maintain a small footprint. The sensor itself is 0.15mm thin. Therefore, it doesn’t cut into space that otherwise is devoted to the battery or tends to result in the larger phone. The 3D Sonic Max will also be able to create the shape of the finger and further look regarding the geometric sign, such as the distance that has been available between the fingertip and middle and can be employed as the layer of identification.

A much larger sensor

The sensor size available on the previous model was 4mm*9mm; however, the latest model has 20mm*30mm, full 16x larger in comparison to the previous model, which makes the orientation of the phone much more prominent in contrast to the previous model. The sensor available in the phone can be operated in a single fiber detection mode or dual finger detection mode that needs both fingers to be available when the user is unlocking the device. The senor available in the latest model has been able to get rid of the small sensor issue as the fingerprints can easily be detected anywhere inside the open box.

The company didn’t disclose the fact that if the latest sensor costs more in comparison to their Old Sonic fingerprint sensor, however, it can be assumed there has been a slight rise in the price. The company also stated the fact that its solution is not only applicable to the Smartphone. It can also be employed for the automotive that has been based upon the security credentials.

When it has been compared to the last-gen 3D Sonic, the Max carries out the ultrasonic identification that has been available within its hardware, instead of relying on algorithm and processing elsewhere on the device. With such functionality, it has been able to make the system even more secure than before by minimizing the probable points of vulnerability.

Qualcomm expects the 3D Sonic Max will grow up commercially in the latest year. From the fact that Samsung used the 3D sonic in his most recent model Galaxy S10 and Note 10+ flagship, there has been no surprise in the fact that phone maker adopts this next-gen component in the upcoming phones. Therefore, at the present instance of time, we need to wait for other companies to make use of a more secure method of ID-us.


From the above information regarding the latest model, it can be assumed that there are several benefits of using the phone. It can be concluded that the sensor available in the phone can be operated in a single fiber detection mode or dual finger detection mode that needs both fingers to be available when the user is unlocking the device. Therefore, it can be said that Qualcomm’s new 3D Sonic Max sensor is massive and tends to attract the minds of the customer to a great extent.
