With the iPhone X, Apple Touch ID dropped and entered into the future biometrics of the future. But came 2021, via MacRumors, as the company was able to introduce Touch ID as an on-screen fingerprint sensor.
The report comes from Ming-Chi Kuo, who bases his prediction on Apple patents, not information coming from the supply chain, which means his info is very speculative. Still, Kuo seems confident that the fingerprint on the screen (FOD) is worth mentioning.
Technically, we predict that four critical technical issues with FPS will improve over the course of 12-18 months, including module thickness, sensor range, power consumption, and lamination yield. That's why we believe Apple will launch the new iPhone equipped with both Face ID and FOD to improve security and convenience thanks to the multi-biometric.
Kuo says that the two systems will complement, not compete, each other. When one system is impractical to use, the other will be available, and vice versa.
In recent years, companies have introduced devices with fingerprint sensors on the screen, while Apple has completely written off fingerprint biometrics for Face ID. One of the major reasons why Apple's mobile lineup (iPhone XS, iPhone XS Max, iPhone XR) uses Face ID is technology is much safer.
As we have learned on several occasions lately, just because Apple has filed a patent does not mean that it will translate into a genuine product. Although Kuo believes a future iPhone will adopt FPS, we would be skeptical now that Apple appears all-in on Face ID.
