Polar ID by Metalenz
Payment grade authentication in a single image.
The world’s only consumer-scale imaging system that senses the full polarization state of light. Polar ID brings payment-grade face authentication to any device, now even under the display.
1 image
recognition and authentication with 1 image, 1 camera + flood illumination. No dot projector
All conditions
secure unlock from dark to daylight
Under OLED
performance maintained under display
Now under display
Polar ID kills the cutout.
The polarization signature of a face survives an OLED panel, so Polar ID can sit entirely beneath the screen. No notch, no punch-hole, no compromise on security: just a seamless display with payment-grade face unlock built in.
Current approaches
Diffraction destroys temporal information
Z-height limitation, cost and complexity
- Face recognition model performs the same
- Polarization signal remains unchanged under the display
- Discrimination between spoof and live is maintained
- Tested on multiple displays with optimized regions from different manufacturers
The product edge
Polar ID is disruptive to the legacy biometric market.
Security + Design + Experience
Request product brief- Industry-leading 0% spoof acceptance rate
- Less than half the size and cost of incumbent structured light, with no dot projector required
- Operates seamlessly under the display, unlocking payment-grade face authentication without giving up screen real estate
- Unlocks trusted autonomy for agentic AI on device, with frictionless authentication
Built for the agentic era
Unlocking trusted autonomy.
When one device unlocks your money, your keys and your identity, and AI agents act on your behalf, weak authentication becomes systemic risk, and trust becomes foundational. Polar ID meets that moment with hardware-grade proof of a real, present human.
The threat
Generative AI has broken weak authentication.
Face swaps, injection attacks and synthetic identities now defeat passwords, PINs and 2D face checks at a cost of pennies per attempt. Polarization tells a living face from a mask or a screen, physically.
The new demand
AI agents need to know you’re still there.
Authorize-once-trust-forever doesn’t work when agents act continuously. Polar ID sensor confirms the right person is present throughout a session, without a wall of consent prompts disrupting your work flow.

01
Compact, easily integrates into the sensor stack
A single, polarized light sensitive metasurface integrated with your sensor + one flood illuminator. Small enough for the most challenging form factors, like laptops and foldables.
02
Secure and Frictionless
Captures the unique polarization signature of a human face, so even sophisticated 3D masks and spoof instruments are detected as non-human.
03
Works anywhere
Secure unlock in any lighting condition, and operates seamlessly under display.
04
Simple and Affordable
A substantially lower price point than structured light, bringing secure face unlock to the hundreds of millions of devices still relying on fingerprint sensors.
