I've always been a bit wary of facial recognition on phones. Honestly, the 2D versions never seemed all that secure to me. You could probably trick some of them with a decent photo, right? I mean, it's just using a camera to see if your face matches a stored image. Not exactly Fort Knox.

However, there's a new system in town that sounds a lot more promising. It's called Polar ID, and it's developed by a company called Metalenz. What makes this tech different? Well, it doesn't just rely on a flat image of your face. It uses polarized light to create a much more detailed 3D map. Think of it like this: instead of just seeing the surface, it's seeing the contours and shape of your face in a much more accurate way.

This isn't some pie-in-the-sky concept either. Metalenz has announced that Polar ID is now in mass production. That means we could start seeing this technology in phones and other devices very soon. If you ask me, it's about time we had a more reliable and secure way to unlock our devices with our faces!

If it works as advertised – and I really hope it does – it could be a game-changer. I can see a future where facial recognition is actually trustworthy, used for everything from unlocking your phone to verifying payments. After all, It's pretty exciting stuff, and I'm eager to see it in action.
