TEMPbadge offers One-Day Self-Expiring Parking Permits. The permits expire automatically and provide a clear visual alert from 50 feet away. When the permit is issued, a clear self-adhesive "timing cover" is applied. As the day progresses, the word "EXPIRED" gradually emerges letter by letter. By the end of the day, the whole word can be seen, so the permit cannot be used the next day.
