Facial recognition is everywhere – unlocking doors, making payments, clocking in at work. It's certainly convenient. But have you noticed that when it comes to critical scenarios like getting an ID card, a driver's license, or passing through immigration, you still have to press your fingerprint?

Why?

Because faces have a natural weakness – they are almost "public." Your face appears on social media, street cameras, and friends' posts – easily copied. AI face-swapping and 3D-printed masks can already fool many ordinary facial recognition systems.

Fingerprints are different. They are not as exposed as faces. Collecting a fingerprint requires physical contact. What's more, the new generation of fingerprint technology can not only read the pattern but also determine whether the finger belongs to a real human.

That's "liveness detection." Chipsailing's glass‑based fingerprint chip uses infrared light to detect blood flow signals beneath the skin. A fake fingerprint made of silicone has no such signal – the device can recognize it immediately.

So, facial recognition works well for everyday convenience, while fingerprints serve for critical identity verification. Together, they provide a more secure solution.

Next time you're asked to press your fingerprint, don't see it as a hassle – it's an extra safety lock for you.
