Abstract

Indicia readers may be configured with two illumination light sources: a primary light source for illuminating primary indicia (e.g., a barcode) and a secondary ultraviolet (UV) light source for revealing secondary indicia (e.g., UV fluorescent watermarks) that are used to protect against counterfeit and fraud. Ultraviolet light can be harmful. The present invention embraces methods and a device for controlling the secondary UV light source to limit UV exposure. When an exposure risks is detected, the UV light source is deactivated.

First claim

The invention claimed is:

1. A computer-implemented method for controlling an indicia reader's illumination, the method comprising:
activating a primary light source to illuminate a primary indicia on an item;
scanning the item's primary indicia with the first light source to produce primary-indicia information;
classifying the item based on the primary-indicia information;
comparing the item's class to classes stored in a memory;
if the item's class matches at least one o…
