After the popularity of e-SIM, smart watches have the ability to independently access the Internet and make phone calls, but even if it is better than Apple's Apple Watch series, it still has no biometric functions such as face or fingerprint recognition. To ensure privacy security, users still enter passwords manually.

However, on December 16, it was reported that the Apple patent just released showed the possibility of introducing an offline camera and a Touch ID into the Apple Watch (iPhone: I don't use an online or offline camera).

Recently, two Apple patents appeared in the United States Patent Office. The first one was discovered by MacRumors, a foreign media, which explained how to add fingerprint recognition function to the power key of Apple Watch. In fact, this solution is to transplant the power key of the iPad Air 4 to the watch. The technology is very mature, and waterproof is not a problem at all. After all, Sony's flagship has used waterproof side fingerprint keys for many years.

Why have other smart watch manufacturers never introduced fingerprint recognition to their watches? For one thing, it may be that the frequency of unlocking the watch is too low. Second, the volume and cost may not be enough.

The second patent was discovered by Apple Insider, a foreign media, with the title of "Electronic Device with Two Segment Display", which can make the screen transparent when needed, so that the camera and flash below can work. In plain English, it is the camera under the screen. The patent mentioned that this technology is also applicable to the iPhone and can be used to eliminate all evil "bangs", but this patent is mainly aimed at the Apple Watch.

With the off screen camera, the watch can make video calls with others without affecting the proportion of the screen, but the view angle is too low, and it may always look at its own big nostril. In addition, wearing a watch, you can take a selfie without being aware of it. Then I am happy to tell others that this is the latest and most awesome Apple Watch Series 10 with an off screen camera and touch ID that the iPhone 13 does not have.
