Holographic gradient identification card

Abstract

The invention discloses a holographic gradient identification card, which comprises a card main body and a card sleeve, wherein the card main body is positioned in the card sleeve and is connected with the card sleeve through a connecting seat; the card main body consists of a substrate, a connecting layer and a three-dimensional grating layer; a chip is arranged in the substrate; the substrate consists of two substrate bodies which are distributed on the left and right sides; the front sides of the two substrate bodies are connected with the connecting layer; the three-dimensional grating layer consists of four three-dimensional grating layers; the back of the first substrate body is provided with a first three-dimensional grating layer; the right side face of the first substrate body is provided with a third three-dimensional grating layer; the back of the second substrate body is provided with a second three-dimensional grating layer; the left side face of the second substrate body is provided with a fourth three-dimensional grating layer; a holographic identifier, an identification card and a detection piece are arranged on the connecting layer; the holographic identifier and the identification card are positioned on one side of the second substrate body; and the detection piece is positioned on one side of the first substrate body. After the first substrate body and the second substrate body are folded, the third three-dimensional grating layer and the fourth three-dimensional grating layer are coplanar; and the identification card and the detection piece are overlapped with each other.

Description

technical field [0001] The invention relates to an anti-counterfeit identification card, specifically a holographic gradient identification card. Background technique [0002] Identification cards are used more and more widely in daily life, such as IC cards, bank cards, shopping cards, etc. In order to prevent criminals from forging identification cards, people will add anti-counterfeiting marks on identification cards. As a method with simple structure and good anti-counterfeiting effect, holographic identification is widely used in identification cards. However, with the maturity of holographic identification technology, anti-counterfeiting through holographic identification alone is becoming weaker and weaker in terms of ensuring the security of identification cards. The use of three-dimensional grating technology for anti-counterfeiting is not only anti-counterfeiting, but also beautiful in appearance. However, the general grating three-dimensional IC card has only o...

AI Technical Summary

Problems solved by technology

However, the general grating three-dimensional IC card has only one anti-counterfeiting grating layer, and the difficulty of imitation is not high, and it is impossible to combine multiple grating layers for anti-counterfeiting

Therefore, whether it is an identification card with only holographic logo or only with three-dimensional grating technology, its anti-counterfeiting effect is not ideal

In addition, the current identification card is only one card with a large area, and it is easy to squeeze the card when carrying it, causing the IC card to bend or even break

Especially in summer, people's clothes have smaller pockets, and it is more inconvenient to carry IC cards
