Plastic identification card having an improved signature panel |
| abstract |
This invention relates to a plastic identification card with an improved signature panel. There is a problem with existig credit cards in that the existing signature can be obscured by printing over with a patch of clay composition similar to that used to provide the original signature panel. A new signature can then be applied. This problem is overcome by providing a signature panel which is sandwiched between the core stock and a protective transparent film. The signature panel comprises a layer of chemicals reactive under the pressure of a signature to release a colored dye conforming with the signature. |
