According to recent updates, Apple is working on optical fingerprint sensing that uses light to read and analyze a fingerprint.
According to the new patents, the technology will cut down some of the issues with light-based fingerprint sensors.
The company stated, “improve the contrast of fingerprint impressions and maintain the compactness of the entire sensing system.”
One implementation of the patent could set a light-emitting layer covered by a transparent layer to illuminate a surface.
According to the source, the company files various patent applications on a weekly basis.
