Embedded Harrington
Harrington Module

Harrington is a self-contained, standalone iris enrollment and authentication system that is offered as a complete reference design. This solution is a superior combination of optical and algorithmic elements that enable absolute security and unmatched ease-of-use.

Harrington includes off-the-shelf near-infrared illumination, a commercially available image sensor, proprietary lensing for image sensor, and leading-edge enrollment and authentication algorithms. This design is ideal for diverse markets, including Medical/Healthcare, Enterprise (including secure printing), Home Security and Lottery/Casino.

A rich variety of system interface topologies enable a simple yet robust messaging interface to the main system controller while on-board algorithm processing minimizes overhead for the main system controller. Dual iris enrollment and single- or dual-iris authentication are supported with software and algorithms that are portable to other OS’s.
