Several expiring-badge styles are available:
Visitor badges are commonly issued on a “temporary” basis for defined periods, purposes, and areas—the permission they grant is temporary and of limited duration. Sometimes visitor badges are issued for recurring visits over a defined time. Either way, their validity typically expires at some point. Because they’re temporary, card issuers need to ensure that visitor badges are not used after expiration.
Visitor badges created using smart and proximity cards can be configured to expire and not read after their coded expiration date. For simpler (non-smart) visitor badges, accommodating the expiration need usually requires a visual signal, so visitor badges have evolved to feature “self-expiring” technology. Self-expiring visitor badges are simple, effective, and affordable. They’re a great way to ensure the issuer knows any visitor’s status—quickly and easily, even at a distant visual glance. These badges automatically expire after a certain number of hours, days, or weeks—preventing the badge from being reused on another day.
This easy-to-use self-expiration badge technology does this by transforming some visual aspect of the card when it expires. That is, it causes the badge color to change or adds markings (revealing a striped pattern or spot indicator) after a prescribed amount of time thus letting everyone know it’s expired, revealing its invalidity and preventing it from being used again after its color has changed.
