Example Embodiment

[0015] Embodiment 1: This embodiment is composed of a substrate 1, an information layer 2, and a covering layer 3. The information layer 2 is composed of a plurality of information blocks, and the information blocks are on the substrate 1. The substrate 1 is made of PVC material with high light reflectivity, and the information layer 2 is made of ink material with low light reflectivity. The covering layer 3 covers the information area of ​​the substrate 1, covering all the substrates and information blocks in the information area. The covering layer 3 adopts an ink material with high transmittance of invisible light and low transmittance of visible light. . The information block on the information card cannot be seen visually.

[0016] An anti-counterfeit magnetic hole 4 or an anti-counterfeit metal strip 7 is also embedded in the substrate 1.

Example Embodiment

[0017] The second embodiment: the difference between this embodiment and the first embodiment is that the same information layer 2 covering layer 3 is cured on the upper and lower sides of the information area of ​​the substrate 1 respectively. The other composition and connection relationship are the same as in the first embodiment.

Example Embodiment

[0018] Embodiment 3: The difference between this embodiment and the first embodiment is that the upper and lower sides of the information card formed by the information layer 2 of the substrate 1 and the covering layer 3 are covered with a transparent anti-wear protective film 5.

Abstract

Implicit information card has a information layer comprising several information blocks fixed onto a substrate and the information layer and the substrate have obvious difference in reflectivity. A shielding layer covers the substrate part and the information chips in information area completely and there are also magnetic anti-fake uholes embedded inside the substrate. The present invention has the advantages of powerful anti-fake capacity, high wear resistance and stable performance. Furthermore, the substrate may be manufactured into non-directional one for convenient use.

Description

technical field [0001] The invention belongs to the synthesis and improvement of barcode cards and photoelectric cards. Background technique [0002] The existing barcode card information is exposed, and there are disadvantages of being afraid of wear and tear, easy to copy, and its identification method is relatively complicated. And the coding of the photoelectric card is also exposed, so it also has the disadvantage of being easily copied. In short, the above two cards have the disadvantages of poor security and weak anti-counterfeiting ability. Contents of the invention [0003] The purpose of the present invention is to develop an invisible information card with invisible information, stable performance, strong anti-counterfeiting ability, long service life, no fear of abrasion and easy recognition. [0004] The composition of the present invention includes a substrate 1, an information layer 2, and a covering layer 3. The information layer 2 is composed of a plural...
