Kodak of Rochester, New York, is taking steps to stop the sales of counterfeit rechargeable batteries, which can lead to poor performance, damage to electronic devices, and overheating. To combat the problem the company is deploying its KODAK TRACELESS System for Anticounterfeiting on KODAK Li-Ion Rechargeable Digital Camera Batteries. The system uses forensically undetectable markers that can be placed into printed materials, product packaging, or components of the product. The markers can be detected only by using secure, hand-held KODAK readers. The system can be used for the protection of a wide range of products and packaging materials, because the markers can be mixed with inks, toners, varnishes, and other items for analog and digital printing, as well as paper pulp, plastics, powders, pigments, liquids, and textiles.
