The fingerprint feature is now supported on thousands of Android devices, but it’s still not available on any Apple devices.
Now, a new patent from Apple suggests that the company is also working on under-screen fingerprinting and that the feature could be on the Apple Watch before the iPhone.
According to PatentlyApple, the Apple patent was filed in the second quarter of 2018 and was recently released in connection with the Apple Watch. The patent describes embedding an antenna in the strap, but says the watch’s display could include “one or more input devices, such as touch sensors, temperature sensors or fingerprint sensors.”
Currently, Apple Watch relies on matching and proximity to the iPhone for authentication, but this is not ideal, and a complex system like Face ID is obviously not suitable for Apple Watch, so the off-screen fingerprint may be a more appropriate solution.
As for the antenna in the strap, Apple points out that the antenna needs some special functions, such as the ability to stretch, bend and bend, while maintaining comfort.
