Qualcomm improves its in-display fingerprint sensor, making it significantly larger in the first place.


Fingerprint sensors have been integrated directly into smartphone screens for a while now, but very few solutions are convincing. Either the detection area is too small, the detection too slow, or the error rate is fundamentally too high. 3D Sonic Max is the name of Qualcomm’s newest solution.

More space, more fingers

The surface on which the finger is recognized has been enlarged 17 times. The user may even have to authenticate with two fingers at the same time. Of course, this increases security. It also makes it easier to locate the area where fingers can be recognized.

Also, all manufacturers can get these Qualcomm fingerprint sensors for their own devices. Maybe Samsung will be there next year too and will rely on the new 3D Sonic Max. However, the first manufacturers of inexpensive devices are already moving away from these sensors, the costs for them seem too high.
