For years, smartphone manufacturers have tried to hide all biometric sensors to offer us interruption-free screens. However, while under-panel fingerprint readers are already common, the secure facial recognition has resisted. Apple continues to rely on its famous Dynamic Island, and Android devices that tested under-screen cameras sacrificed photo quality and security.
All this could be about to change thanks to Metalenz, an optical company that has presented its revolutionary system at Display Week Polar ID Under Display. Unlike traditional methods, this solution requires no cutting or drilling, and promises an optimal level of security for mobile payments without ruining the visual experience of a panel. OLED on.
Goodbye to conventional cameras: the magic of polarized light
The key to this advance lies in leaving classic sensors behind. Instead, Metalenz uses metasurfaces, flat and microscopic optics, along with its technology PolarEyes. This system is capable of capturing the polarized light of the scene instantly. This detail is vital: the polarization signal allows the material to be distinguished real than what is focusedachieving a zero success rate against fraud attempts with masks or two-dimensional photographs.
As if that were not enough, the company ensures that its technology works without problems through active screens, without losing intensity in the biometric signal. Although it sounds spectacular, as is often the case with these early announcements, we still need to check how it behaves in real-world scenarios and confirm that it does not increase the cost of the terminals. If they manage to convince manufacturers, the next high-end mobile phones will adopt this all-screen design.
Would you be willing to trust an invisible sensor to protect your payments if it means the end to cuts to your device for good?
