Problems solved by technology

The traditional IC card will peel off the surface after being used for a long time, resulting in damage to the card
In addition, it is unavoidable that the card will suffer from water immersion during the use of the card. Since the layers of the IC card are mostly glued together, it is easy to cause the layers to separate and fall off under the action of water.

Embodiment 1

[0019] Embodiment 1: refer to figure 1 with figure 2 , an IC card, comprising a card body 8, the card body consists of a first hydrophobic layer 1, a first protective layer 2, a first printed layer 3, a chip layer 4, a second printed layer 5, a second protective layer 6, a second The hydrophobic layer 7 is laminated sequentially, and the side of the card body 8 is laminated with an anti-peeling collar 9 .

[0020] After the traditional IC card is used for a period of time, the surface layer of the IC card is prone to peeling off, and the surface layer peeling off is most likely to occur on the side of the IC card, that is, the edge position of each layer. By being provided with an anti-peeling collar 9, it can effectively adhere Fix each layer of the IC card, improve the adhesion of each layer of the IC card at the edge, and prevent the surface layer of the IC card from peeling off.

[0021] In order to prevent the IC card from being peeled off due to water immersion during...

Embodiment 2

[0028] Embodiment 2, with reference to figure 1 with image 3 , the present embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, in order to reduce the aging effect of external ultraviolet rays on the IC card and prolong the service life of the IC card, further, the first protective layer 2 and the second protective layer The outer surface of 6 is vapor-deposited with the first anti-ultraviolet layer 14 and the second anti-ultraviolet layer 15 respectively, the first anti-ultraviolet layer 14 and the second anti-ultraviolet layer 15 have the same composition and structure, the first anti-ultraviolet layer 14 and the second anti-ultraviolet layer Layer 15 is any one of silicon oxide / titanium dioxide binary vapor deposition layer and titanium dioxide / tungsten trioxide binary vapor deposition layer.

[0029] In order to facilitate the collection of IC cards, further, the card body 8 is also provided with a hanging hole 10 . Multiple IC ca...

Abstract

The invention relates to the field of smart cards, in particular to an IC card. According to the following technical scheme, the IC card includes a card body, and the card body is formed by sequentially laminating a first hydrophobic layer, a first protective layer, a first printing layer, a chip layer, a second printing layer, a second protective layer and a second hydrophobic layer. An anti-stripping sleeve ring is arranged on the side surface of the card body in a laminated mode. According to the IC card, the surface layer of the IC card can be effectively prevented from being stripped offand the IC card has a waterproof function, the aging effect of ultraviolet rays on the printing layers of the IC card can be reduced, and the service life of the IC card is prolonged.

Description

technical field [0001] The invention relates to the field of smart cards, in particular to an IC card. Background technique [0002] Smart card stock, also called IC card, is a card stock that can be used in various VIP cards, bank cards, social security cards, bus cards, ID cards, door cards, etc. The surface layer of the traditional IC card will peel off after a long time of use, resulting in damage to the card. In addition, it is unavoidable to suffer from water immersion during the use of the card. Since the layers of the IC card are mostly glued together, the layers are easily separated and peeled off under the action of water. [0003] Therefore need to carry out effective improvement to existing IC card, to improve the service life of IC card, satisfy the use demand of consumer. Contents of the invention [0004] The problem to be solved by the present invention is to provide an IC card. [0005] In order to solve the above problems, the present invention adopts ...
