Problems solved by technology
[0005] However, when the above-mentioned fingerprint identification technology is applied in electronic equipment, it often cannot be well integrated with electronic equipment.
The usual practice is to add a separate fingerprint recognition module to the electronic device, which increases the volume of the electronic device, is not conducive to the miniaturization of the electronic device, and leads to a decrease in the integration of the electronic device, and the fingerprint recognition module as a separate module is vulnerable to Attacks and violent dismantling are not conducive to the protection of personal information
