A high-security card and its manufacturing method

Abstract

The invention discloses a high-security identification card and a manufacturing method thereof. Among them, the high-security card includes a card body structure and a protective film combined with the upper and lower surfaces of the card body structure, wherein: the card body structure includes a laminated multi-layer card body material, and the card body structure includes one or more layers of laser The etching material; the protective film and the card body structure are combined through a lamination process; the card visual reading personal information is respectively arranged on the multi-layer card body material and the protective film of the card body structure. The above-mentioned high-security card, by improving the card body structure and protective film, starting from the loading and protection of the visually read personal information of the PET card in the multi-layer structure of the card, has realized embedded color laser printing and laser engraving , color inkjet and other personalization techniques; hidden coded information is added to the surface of the component packaging layer, and the hidden coded information is associated with the card's visually read personal information or other information, so that the card-related personal information runs through the entire card in the card structure layer.

Description

technical field [0001] The invention relates to a high-security card and a production method of the high-security card. Background technique [0002] With the development of society and economy, forgery of various identity documents and false use of other people's identity information to carry out various illegal and criminal activities remain high. In order to curb the occurrence of the above phenomenon, countries attach great importance to the security and anti-counterfeiting of important identity documents such as passports, ID cards and driver's licenses. Illegal use by counterfeiting, falsification and impostors. [0003] PET (polyethylene terephthalate) card production technology is a kind of card making technology that is often used in domestic legal documents. Such as figure 1 and figure 2 As shown, the existing PET card includes a card body material 10 and a PET protective film 20 covering the upper and lower surfaces of the card body material 10 respectively. ...

AI Technical Summary

Problems solved by technology

[0013] (2) The protective film on the surface of the card lacks protective measures, counterfeiting is not easy to identify, and there is a risk of counterfeiting

All kinds of glue-coated PET protective films on the market will also show high transparency after being compounded with card body materials. Therefore, the existing PET card protective films have no clear appearance characteristics, and it is difficult to distinguish them from counterfeit materials on the market.

[0015] The material of the protective layer itself has a certain thickness, and it is still possible for the counterfeiter to erase the photo by mechanical or chemical means to replace it, and then attach a layer of transparent PET glued protective film on the surface, which has the risk of alteration

[0016] (3) Visual reading of personal information lacks other means of association and verification

[0017] All the visually read personal information of the PET card is loaded on the inner surface of the PET protective film. If it is tampered with or altered, in the case of a chip reading failure, there is no other effective means of association and verification.
