  • Publication number: 20030205623
    Abstract: The invention provides a method of manufacturing a card such as bankcards provided with an anti-counterfeit differentiable mark. A stamper is fabricated by engraving and plate-making methods, the stamper being engraved with a feature pattern provided by a client, such as bank logo and trademarks. The feature pattern of the stamper is transferred onto a surface of a card by injection molding. A metallic layer is formed on the card by plating. A printing layer is finally formed on the card by printing. Hence fabricated, the card is provided with a text and/or graphics pattern similar to the effects of a hologram pattern.

  • Publication number: 20030205624
    Abstract: A card fabrication method of the invention uses ABS plastics to form a card body of the card. The fabrication method of the invention is used to manufacture various types of cards such as bankcards. The ABS material is injection molded to form the card body. While injection molding the card body, different additives and colorant agents are incorporated to the ABS to obtain a card body that is easily differentiated via a specific color aspect. The specific color aspect is in accordance with a specific card emitter. Printing is simultaneously performed on two faces of the card body to achieve the differentiable card. By attributing specific color aspects to specific card emitters and, counterfeit cards is therefore easily differentiated from authentic cards by the color aspect of the card body.
