  • Method of manufacturing cards and other documents
    Patent number: 4006050
    Abstract: A card or other document is produced by forming by xerography an image of security matter on a transfer sheet and subsequently transferring the image to a plastics base. The security matter can be, for example, a photograph, signature or fingerprint of the intended holder of the card. The resulting card is intended to be proof against fraud to a large extent, because the image cannot be easily altered.
