Body Temp Document Security

Boise Paper's CheckProtect with HeatStar Security Papers was developed in response to the growing epidemic of document fraud. Boise says it is the first paper manufacturer to provide the security document market with a special thermochromatic ink incorporated in the finished product. Previously, thermochromatic ink was offered only as a custom add-on to security products, making it more expensive to use and mass produce. HeatStar is a blue-star pattern in blended, heat-sensitive thermochromatic ink on the backside of Boise's white CheckProtect paper. It is activated by body heat, which can be applied by rubbing one's finger over the paper. The blue-star ink begins to decolor at 75°F and completely disappears at 91°F. The ink's color-changing property allows for easy verification and authentication of a document. Boise says the paper—which is impossible to duplicate with copiers, scanners, printers and other digital media—is suited for checks, gift certificates, money orders, vital records, ID cards and more. www.boiseheatstar.com
