| titleOfInvention | Security identification badge |
| abstract | A self-expiring Security Identification Badge is provided. The badge includes a base substrate (11) having a void indicia area (14). Also included is an ink substrate (30) having an expired indicia area (34) of a soluble ink and an adhesive surface (32). Also included is an overlay substrate (40) having an ink dissolver (42) and a display surface (44). When the I.D. Badge is issued, the inked substrate (30) is attached to the base substrate (11), with the inked substrate (30) covering the void indicia area (14). The overlay substrate (40) is then placed over and attached to the inked substrate (30), with the ink dissolver (42) in contact with the soluble ink (34) of the inked substrate (30). The ink dissolver (42) of the overlay substrate (40) contacts and coats with the soluble ink (34) of the inked substrate (30) to dissolve the ink and allow the ink to migrate through the overlay substrate (40) to the display surface (44), where it can be visually perceived, in a preselected time interval. |
