Metalenz has developed Polar ID, a face-scanning technology that works even when the camera is hidden under the display. This breakthrough was announced on May 4, 2026. The innovation is set to revolutionize smartphone security.
The technology uses a polarisation camera and a unique algorithm to detect and authenticate faces. By doing so, it enables devices to verify identities without the need for a visible camera.
Polar ID achieves this by leveraging the polarisation properties of light. When light bounces off a face, its polarisation changes. The camera captures these changes and uses them to create a 3D map of the face. This map is then used to authenticate the user's identity.
The technology has the potential to enhance user experience by allowing for more seamless and secure biometric authentication. It also opens up new design possibilities for device manufacturers.
As the technology continues to evolve, it is likely to have significant implications for the smartphone industry. With Polar ID, devices can be designed with a more minimalist approach, improving aesthetics and user experience.
The adoption of Polar ID could lead to a shift away from traditional authentication methods, such as passwords and fingerprint scanning. As a result, smartphones may become even more secure and user-friendly.
How does Polar ID work? Polar ID uses a polarisation camera and algorithm to detect changes in light polarisation when it bounces off a face, creating a 3D map for authentication.
Is Polar ID more secure than traditional Face ID? Polar ID's unique approach to face scanning provides an additional layer of security, making it potentially more secure than traditional methods.
Will Polar ID be available on existing devices? While it's unclear, Metalenz's technology is likely to be integrated into future devices, potentially through software updates or new hardware designs.
