Visitor badges that expire on their own
Two-part system: This badge back is not a full solution. A compatible badge front is required for use.
The Genuine TEMPbadge T6031A is a 1 15/16 x 2 7/8 inch self-expiring adhesive badge back that reveals the word EXPIRED, sold in a box of 1,000.
How it works
This universal back supplies the timing chemistry for TEMPbadge two-part expiring badges. Write or print visitor information on a compatible TEMPbadge front, press it onto the back, and the timer starts. Instead of plain stripes, the word EXPIRED appears through the front as the badge expires: half-day fronts expire in about 4-6 hours, 1-day fronts expire overnight in about 10-15 hours, and 7-day fronts expire in about 4-7 days.
What you need
This is the back half of a two-part badge. You also need a TEMPbadge expiring front in the time frame you want (half-day, 1-day, or 7-day) to complete each badge.

The color builds until the badge reads expired
Once the badge is activated, dye migrates at a steady rate and the expiring area shades from white to pink to red. These are the actual TEMPbadge lab shade charts; the dashed box marks the recommended expiration time.

Times are approximate. The timer is chemical: warmth and humidity speed it up, cool dry air slows it down.
Expiration times are guidelines, not exact clocks. The timer is chemical and made for indoor use: warmer or more humid air runs it faster, cooler and drier air runs it slower. A 1-Day badge can expire in as little as 10 hours.
