The 1000 removable, round double-labels 4852E-THR from Avery with a diameter of 22 mm make it easier for you to organize visitors with temporary access authorizations.
The round labels are equipped with self-expiring “VOID” technology: With the innovative Expiring Technology™, the inscription “VOID” becomes clearly visible after approx. 4-6 hours - depending on temperature. (At low temperatures (below 20°C), it may take more than 6 hours). A specially developed red ink is activated on contact with the label's adhesive, which gradually becomes more and more visible.

This is how it works:
- First apply the red dot, e.g. to the name tag
- Then stick the white dot directly onto the red dot to activate the 24-hour process
- Distribute the name badges to your visitors
- After approx. 4 to 6 hours, the word “VOID” will gradually appear on the right-hand side of the badge.
- The badge expires completely the next day.

The self-expiring, round ""VOID"" labels are perfect for secure visitor management, for application on visitor badges for time-limited access authorization of e.g. business areas, schools, events and all places with public traffic. But also for all applications where a time limit applies and needs to be clearly shown.
