The fingerprint scanner behind the screen is the Duke Nukem Forever of the mobile market. It was a promise for years and recently he was there. The first rumors about the technology date from about four years ago and since then there are always rumors that the next generation of high-end smartphones will have a fingerprint scanner behind the screen.
Synaptics was the first to show its Clear ID sensor for unlocking with the fingerprint at the beginning of this year by pressing the screen. It is now clear that all suppliers of biometric authenticators are working on this technique, although the implementation differs.
For this story we have borrowed a Vivo X21 smartphone from Chocoball for which many thanks!
