Apple plans to use full-screen fingerprint scanners in the iPhone 2021 release.

The company will also maintain a Face ID authentication system that will work in parallel. Also, the possibility of simultaneous use of the fingerprint scanner and face, which should increase the level of security.

Fingerprint scanners built into the display began to emerge last year, such as the Vivo X20 Plus UD. Apple is also working on a similar technology, as indicated by a patent registered in 2017. However, the company is in no hurry to use it on its devices.

This may be due to the underperformance of existing solutions. According to Ming-Chi Kuo, technical problems will be overcome by 2021.
