When an adhesive timing cover is applied to the front of the badge, a color change appears in a half-day (4 hours) so the badge cannot be reused. No need to worry about unauthorized re-use of uncollected badges. Patented color change is highly visible from a distance. Perfect for students who forget their school ID.
