The magic touch: The reasons behind the increasing use of ultrasonic fingerprint sensors in smartphones. The 3D Sonic Gen 2 sensor from Qualcomm Technologies recognizes your unique fingerprint and protects your data using an ultrasonic pulse.
Did you know your fingerprint can protect your personal data? Qualcomm Technologies researchers created fingerprint sensor technology to unlock your phone with a single touch and improve device security because they know how important it is to quickly and securely access all of your smartphone data.
Recent years have seen OEMs substantially redesign smartphone accessibility and access control with this 3D Sonic fingerprint sensors. Additionally, the Qualcomm 3D Sonic Gen 2 increases the standard for how fingerprint detecting technology improves the use of smartphones.
Even if there are 8 billion fingerprints in the world, a photocopy of your fingerprint may still be used to unlock smartphones with older fingerprint sensors. However, this isn’t the case with devices with Qualcomm 3D Sonic Gen 2. Using sound waves, the Qualcomm 3D Sonic Gen 2 sensor reads the valleys and ridges that are distinctive to your fingerprint by sending an ultrasonic pulse against your finger in place of conventional picture scans.
When everything is on it phones
As the newest Snapdragon mobile platforms make it devices smarter with on-device AI, the importance of mobile devices in it lives will only grow. To showed how a smartphone user may ask their AI assistant to divide the bill and compute the tip at a restaurant by only snapping a photo of the receipt at Snapdragon Summit 2024. You may then pay your portion of the bill with a single tap using your phone’s payment details.
In recent years, mobile wallets and payments have grown more popular. In addition to being quick, simple, and comfortable to use, not having to carry many cards has changed the game. Your phone contains everything you need, therefore no wallet. By 2027, mobile payments will top $1 trillion in US POS transactions. To must make sure that the limit access on Qualcomm mobile devices since there is an incredible amount of money and to personal information in circulation.
How Qualcomm 3D Sonic Gen 2 protects smartphones

Qualcomm 3D Sonic fingerprint sensors build a highly comprehensive 3D map of your fingerprint, including its ridges and pores, using ultrasonic sound waves. Reliable identification is made possible by this degree of detail, even in strong sunshine or with damp fingertips.
With only three touches, you can now set up your fingerprint ten times faster than with earlier iterations. This is so that the Qualcomm 3D Sonic Gen 2 sensor can process authentication more quickly by capturing more data points and area from the user’s finger to its wider recognition surface. Because of the improved sensor’s ability to recognize your fingerprint more precisely, unlocking your phone has never been easier.
Ultrasonic pulse fingerprint detection is now commonplace on many OEM flagship goods
Ultrasonic pulse is now the go-to technique for fingerprint recognition beneath smartphone screens with to recent developments in flexible OLED display technology. The Qualcomm 3D Sonic Gen 2 sensor’s ultra-thin 0.2mm form size and optical isolation from the OLED display make it ideal for integration with smartphones that have these flexible OLED screens. This guarantees that it may be effortlessly included into the gadget, permitting svelte and fashionable designs without compromising on functionality.
Numerous smartphone manufacturers have already noticed. Ultrasonic fingerprint sensors are available in new releases like:
- Google Pixel 9 series
- Samsung Galaxy S24
- OPPO Realme GT7 Pro
- IQOO 13 Pro
- Xiaomi Mi 15 and Mi 15 Pro
- Honor Magic 7 series
In the smartphone market, this technology is quickly taking the lead. More customers will seek out gadgets that are not only easy to use but also ones that they can feel secure using since they know their data is protected.
3D Sonic Gen 2
The quickest Ultrasonic In-Display Fingerprint Sensor in the world
The Qualcomm 3D Sonic Gen 2 sends an ultrasonic pulse against the finger, using sound waves to scan the ridges and valleys of the finger. For rapid and simple security performance, the 3D ultrasonic pulse reflection produces a detailed 64mm2 copy of the scanned fingerprint.
Advantages
Sleek security solution
A smooth and elegant appearance is made possible by integrating the 3D Sonic fingerprint reader beneath a smartphone‘s screen. 3D Sonic scans the pores of a user’s finger to create an incredibly realistic image using acoustics, or sound waves, and technical advancements. Modern form factors like complete glass edge-to-edge displays are made possible by the very thin (0.2 mm) sensor, which is also broadly applicable to flexible OLED displays.
Security against spoofing
Use the most cutting-edge fingerprint security technology possible to protect a user’s identity. Instead of using optical solutions, which expose users to spoofing, 3D Sonic employs acoustic-based technology that mimics the distinctive characteristics of each user’s fingerprint.
With its built-in anti-spoofing feature, 3D Sonic satisfies the strictest security requirements for mobile devices, thwarting phone photos and finger molds.
Excellent performance
In addition to being quicker than conventional systems when fingers are wet, 3D Sonic offers exceptional performance in a variety of operating circumstances, including dry, wet, and even contamination exposure.
