Isorg launches multi-finger biometric sensor module for smartphones



Isorg will demonstrate its new Fingerprint-on-Display (FoD) module, which the company says delivers improved multi-finger authentication on smartphones, at the upcoming CES 2020 event in Las Vegas.

In contrast with fingerprint modules in currently available smartphones, which are restricted to a single finger and a surface area of less than 10 mm by 10 mm, Isorg’s FoD module support authentication with up to four fingers across the whole of a 6-inch or larger display area. The module is only 0.3 mm thick, which the company says makes integration easy for OEMs.

The company says the module responds to OEM and end-user demands for high security technologies that can support fingerprint sensing on a large surface area.

“Isorg is excited to demonstrate what could be the future in multi-fingerprint-on-display security to strengthen authentication on smartphones and wearable devices,” comments Jean-Yves Gomez, CEO of Isorg. “Our Fingerprint-on-Display module provides OEMs with a complete solution. In addition to the image sensor, it includes other hardware: optimized thin film optical filters developed in-house and driving electronics, as well as software from our industrial partners covering the interface with smartphone OS and the matching algorithm. Isorg has achieved a significant milestone in designing a scalable FoD solution that provides excellent performance results, it is compatible with foldable displays and easier to implement than existing technologies.”

The technology could enhance the security of mobile banking and payments, health monitoring, and smart home applications on mobile devices, and could also be deployed to wearables for access control, the company suggests.

Gomez notes in the announcement that Isorg’s organic photodetector (OPD) technology is used with rigid glass and polyimide substrate sensors, and compatible with flexible curved-edge displays or foldable devices.

Samples of the module will be available to OEMs in spring 2020, and the company is also extending development for different applications in the biometric security market.
