With CL-2020 time clocks employees look into the time clock display and within seconds they are identified and clocked in or clocked out.CL-2020 dual-camera system performs a 3-D analysis of the 60 facial points unique to each employee. These groups of facial points are recorded and stored as data algorithms in the time clock. As a result, employee images are collected only as digitally encoded information, so they cannot be reproduced as photographic images.
