Secure Temp IDs
January 23, 2002
The VOIDbadge from TEMTEC is a plastic badge pre-printed VOID and valid only with a 2-part authorization sticker covering the VOID area. The sticker called a TIMEtoken will automatically expire by turning red after a specific time of one day, one week or one month. Any photo ID can also become a VOIDbadge.
