TEMPbadge originated the patented Visually Changing Paper (VCP) technology. This technology uses coating and printing capabilities to create materials that reveal a message, color or design after a specified time period. Specifically, a chemical reaction causes the badge to be visibly altered in its appearance either through a changed color (e.g. white to blue in our LIGHTbadge) or by the appearance of slanted red lines in our TIMEbadges. This changed color indicates the badge is "VOID".
TEMPbadge Self-Expiring Badges can expire immediately (LIGHTbadges exposed to ultra-violet rays) or over a half-day (4 hours), full day (18 hours), one week (7 days) , or one month (30 days) using our TIMEbadge product line... and are used as temporary identification for visitors, vendors, temporary employees and contractors.
Our product line includes several hundred products including self-expiring badges, security seals, parking permits and wristbands designed for visitor control in financial, commercial, governmental and educational facilities as well as meeting/convention sites.
