Who has permission to be in your building? How do you know? Stop visitors from sneaking in without signing in. Our Expiring Visitor Badges are valid today and void tomorrow. They change color overnight from white to showing a bright pink “VOID” message. This prevents visitor badge reuse and unauthorized access to your building. We offer three different versions of these magical visitor badges. Each has a special advantage to suit your situation: (1) Tab = one-piece activation. (2) Tandem = extra security. (3) Full = high visibility. All are compatible with your current software and printer. Get free samples.
