Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

The existing smart card with mirror effect can be manufactured by two methods, one is that patterns are directly printed on a conventional mirror substrate and laminated with a film to form a card body, and the surface of the smart card can not achieve the effect of clearly reflecting images due to the limitation of processing technology and used materials.

The other manufacturing method is to directly inlay a glass mirror on the card body, so that the card has a mirror effect. The smart card manufactured by the method can have good mirror effect, but simultaneously, the glass mirror has certain thickness, so the smart card can only be applied to a non-contact card body or other propaganda card bodies without limiting the thickness, and cannot be applied to the card bodies with the conventional standard thickness.

In view of this, referring to fig. 1, the present application provides a smart card, which includes a body layer 1 and a mirror layer 2 stacked together, where the mirror layer 2 includes a primer layer 21 and an electroplated layer 22 stacked together, and the electroplated layer 22 is located on a side of the primer layer 21 away from the body layer 1. The body layer 1 is used for writing or outputting specific data information, and includes a circuit layer 11, a print layer 12, and a protective layer 13, which are stacked. Wherein the plating layer 22 includes a first surface 221 facing away from the primer coating 21, and the first surface 221 is a smooth surface, so that the light incident on the first surface 221 generates a mirror reflection.

The body layer 1 is the basis of the smart card, and the circuit layer 11 in the body layer 1 is used for storing corresponding data, and the stored data generally includes but is not limited to: the algorithm for verifying the authority of the card reader, the verified key, the card number and the data in the card (for example, a bus card can store the balance and the card transaction date, a card in a parking lot can store the entrance time, a dining card can store the residual amount and the user information, etc.). The printed layer 12 is fixedly connected with the circuit layer 11 and is used for covering related circuits, so that the attractiveness of the smart card is enhanced. Wherein the material of the print layer 12 includes, but is not limited to, white PVC, colored PVC, clear PVC, PET, PETG, PLA, and the like. The protective layer 13 is connected and fixed with the printing layer 12 to protect the body layer 1, and the protective layer 13 is usually made of transparent material so that people can clearly see the printing content in the body layer 1.

The body layer 1 and the mirror layer 2 are stacked in a thickness direction X and are connected and fixed to each other, and the body layer 1 and the mirror layer 2 have an upper surface and a lower surface, respectively, in the thickness direction X shown in fig. 1. In general, the upper surface of the mirror layer 2 serves as the front surface of the smart card, the lower surface of the body layer 1 serves as the back surface of the smart card, and the edges of the mirror layer 2 and the body layer 1 are aligned with each other in the thickness direction X. In one embodiment, the side of the body layer 1 facing away from the mirror layer 2 in the thickness direction X is further provided with a back element layer 14. Optionally, the back element layer 14 includes one or more of a magnetic stripe 141, a signature strip 142, and a security label 143.

The mirror layer is used for showing a mirror effect, and the priming coating 21 in the mirror layer is arranged on the upper surface of the body layer 1 and plays a transition role. Specifically, the arrangement of the primer coating 21 can reduce the electroplating difficulty and improve the processing reliability while protecting the upper surface of the body layer 1. In addition, the upper surface of the primer coat 21 is a flat surface, so that the plating precision can be improved, and the leveling processing of the plating layer 22 is facilitated. The electroplated layer 22 is located at the top of the smart card, and is manufactured by electroplating a layer of metal substance on the priming coating 21, and the electroplating method can be a vacuum spraying process, wherein the vacuum spraying process can be a magnetron sputtering coating process. The plating layer 22 itself is made of metal and the upper surface is a smooth plane, so the upper surface of the plating layer 22 will exhibit a mirror effect. Meanwhile, other film layers do not exist above the electroplated layer 22, so that the display effect of the electroplated layer 22 is not influenced by other film layers, related images can be clearly reflected, and the mirror surface effect is strong. Meanwhile, the mirror layer in the embodiment of the application is manufactured and formed in an electroplating mode, so that the thickness of the mirror layer is smaller and excessive influence on the thickness of the smart card can be avoided compared with a traditional mirror inlaying process. Meanwhile, the material and the thickness of the film layer in the body layer 1 do not need to be adjusted, and the universality is high.

In the embodiment of the application, the surface of the smart card can show a mirror effect on the premise of not changing the thickness of the film layer in the body layer 1 and the production process, and the smart card is suitable for smart cards with different sizes and has strong practicability. Meanwhile, the electroplated layer 22 in the mirror sub-layer is formed by an electroplating method, the thickness is small, and other film layers do not exist above the electroplated layer 22, so that related images can be clearly reflected, and a strong mirror surface effect is achieved.

Referring to fig. 3, in some embodiments, the printing layer 12 includes a first printing layer 121 and a second printing layer 122 respectively disposed on two sides of the circuit layer 11, the protection layer 13 includes a first protection layer 131 disposed on a side of the first printing layer 121 away from the circuit layer 11, and a second protection layer 132 disposed on a side of the second printing layer 122 away from the dot circuit layer, and the primer layer 21 is disposed on a side of the first protection layer 131 away from the first printing layer 121.

The intelligent card in the embodiment of the application is a double-interface integrated intelligent card, is a card with contact and non-contact interface communication, integrates the use convenience of the non-contact intelligent card and the safety and reliability of the contact intelligent card into a whole, enables the non-contact intelligent card to be an excellent carrier with multiple functions, and is the main development direction of the future intelligent card. The smart card in the embodiment of the application is flexible and convenient to apply, can optionally adopt a contact or non-contact interaction mode according to different application conditions and requirements, is favorable for reducing the operation cost, and has stronger anti-damage and anti-interference capabilities.

Next, the present application will specifically describe the manufacturing process of the smart card

S1, first, front-back printing is performed on the substrate according to the conventional production flow to obtain the first print layer 121 and the second print layer 122.

And S2, manufacturing and obtaining the middle winding layer, namely the circuit layer 11, according to the requirements.

S3, forming a stacked protective film on the surfaces of the first printed layer 121 and the second printed layer 122 away from the circuit layer 11, to obtain a first protective layer 131 and a second protective layer 132, respectively.

And S4, performing electric welding alignment on the obtained multiple film layers, and laminating to form a body layer 1 with a larger size. Wherein, in the laminating process, the surface of the body layer 1 can use both matte effect and smooth effect.

S5, the upper surface of the first protective layer 131 is subjected to a primer treatment, thereby forming the primer layer 21.

S6, plating is performed on the upper surface of the primer layer 21 to form a plating layer 22.

And S7, cutting the large-size smart card into a plurality of small-size smart cards.

And S8, performing hot-attaching ironing and other processing on the smart card.

And S9, detecting the card.

According to the manufacturing process of the smart card, the smart card is manufactured by the processes of laminating and the like to complete the large-size body layer 1, then the lens layer 2 is manufactured on the large-size body layer 1, and finally the smart card is cut to form a plurality of smart cards. Therefore, the mirror layer 2 is not subjected to external force such as lamination, and damage to the mirror layer 2 is avoided.

Referring to fig. 4, in some embodiments, a third protection layer 133 is disposed on a side of the second protection layer 132 away from the circuit layer 11, and the third protection layer 133 and the second protection layer 132 are releasably attached. The third protection layer 133 is disposed on the back surface of the smart card to protect the smart card from being damaged by electroplating, particularly, the mirror layer needs to be electroplated. Therefore, the third protective layer 133 is arranged to prevent electroplating pollution and prevent scratches. After the smart card is manufactured, the third protection layer 133 can be manually peeled off and taken down to prevent the third protection layer 133 from influencing the use hand feeling of the smart card.

Referring to fig. 4 and 5, in some embodiments, the first printing layer 121 includes a first printing surface 1211, the first protection layer 131 is disposed on the first printing surface 1211, the first printing surface 1211 includes a color portion 1212, and the color portion 1212 at least partially overlaps with an orthographic projection of the plating layer 22 on the circuit layer 11.

The mirror effect of the smart card is not a single silver option, and other colors can be presented, wherein the presentable colors include, but are not limited to, gold, red, blue, green, and rose gold. The color expression principle is that the base color of the plating layer 22 is expressed by the plating layer 22, and the base color of the plating layer 22 may be the color of the first printing surface 1211 of the first printing layer 121 or the color naturally expressed by the base of the first printing layer 121. For example, if the first printing surface 1211 is purple, purple color will be superimposed with the color of the plating layer 22 itself through the translucent primer coating 21 to present a silver purple effect, and the other colors are sequentially reproduced according to the principle of color superimposition.

Optionally, the first printing layer may also be made of a colored opaque material, and in the embodiment of the present application, a mirror effect with different colors is realized by changing the color of the material of the first printing layer. Specifically, when the first printing layer 121 is made of a colored opaque material, the first printing layer 1211 is formed without patterning the first printing layer 121, and a colored mirror effect can be exhibited only by superimposing the color of the substrate of the first printing layer 121 and the color of the plating layer 22. When the first printing layer 121 adopts a transparent substrate, the color mirror effect cannot be exhibited only by the substrate color of the first printing layer 121, so that the first printing layer 121 needs to be patterned to form the first printing layer 1211, and the color mirror effect can be exhibited by the superposition of the color of the first printing layer 1211 and the color of the plating layer 22.

In the embodiment of the present invention, at least a portion of the first printing surface 1211 is configured as the color portion 1212, and the color portion 1212 and the orthographic projection of the plating layer 22 on the circuit layer 11 are at least partially overlapped to form a more beautiful mirror effect. Optionally, the colored portion 1212 and the plated portion completely coincide with each other in an orthogonal projection of the circuit layer 11.

Referring to fig. 4 and 6, in some embodiments, the mirror layer 2 is located in the outer contour of the body layer 1 or the front outline of the mirror layer 1 coincides with the outer contour of the body layer 1. The size of the mirror layer 2 is determined according to the actual use requirement, and for example, the size of the mirror layer 2 can be set to be the same as that of the body layer 1, and the mirror layer 2 completely covers the body layer 1, so as to form a full-scale mirror effect, as shown in fig. 4. It is also possible to reduce the size of the mirror layer 2 such that the mirror layer 2 covers part of the body layer 1, thereby creating a partial mirror effect, as shown in figure 6.

Referring to fig. 7, in some embodiments, the mirror layer 2 further includes a hard coating layer 23, and the hard coating layer 23 is disposed on a side of the electroplated layer 22 facing away from the primer coating 21. The hard coating 23 is made of a high-transparency material, so that the scratch-resistant effect of the smart card can be improved while the mirror effect is not affected, and the service life of the upper surface of the mirror layer 2 is prolonged.

Referring to fig. 8, in some embodiments, the smart card further includes a chip 3, and the chip 3 is disposed on a side of the hardened coating 23 facing away from the plating layer 22. Compared with a magnetic stripe card, the smart card with the chip 3 as a medium has higher security and stronger confidentiality, and is not easy to clone and copy. For a smart card with full-size mirror effect and some partial mirror effect, the chip 3 may be disposed on the upper surface of the mirror layer 2, and some related information mentioned in the foregoing, such as a bank card number, logo, etc., may also be disposed on the upper surface of the mirror layer 2. The processing mode can adopt the processes such as silk-screen printing (UV drying mode) and the like, and the application does not limit the processes.

Referring to fig. 9, in some embodiments, for a partial mirror effect smart card, an orthographic projection of the mirror layer 2 on the body layer 1 is located within an outer contour of the body layer 1, and the chip 3 is disposed on the same side as the mirror layer and located on the upper surface of the body layer 1, wherein the chip 3 and the orthographic projection of the mirror layer 2 on the body layer 1 do not overlap. The chip 3 is disposed in a region other than the mirror layer 2, and the positions thereof do not interfere with each other. This design can avoid the influence of the chip 3 on the mirror effect and improve the display effect of the mirror layer 2. Optionally, the chip 3 may also be disposed on a side of the body layer 1 facing away from the mirror layer 2, i.e., the chip 3 and the mirror layer 2 are disposed on opposite sides of the body layer 1.

In some embodiments, for a partial mirror effect smart card, the smart card may further include a pattern layer, the pattern layer and the mirror layer 2 are located on the same side of the body layer 1, and the pattern layer and the orthographic projection of the mirror layer 2 on the body layer 1 do not overlap. The pattern layer is not shown in the figure, and includes, but is not limited to, information related to a bank card number, a bank name, a logo mark, and the like, which is generally required to be disposed outside the mirror layer 2, so that the embodiment of the present application disposes the pattern layer outside the mirror layer 2. During manufacturing, the printing process of the first printing layer 121 in the body layer 1 is the same as the conventional process, i.e., the base color needs to be printed in advance to print the relevant information in the pattern layer, which is not described herein again.

In some embodiments, the plating layer 22 material is one or more of indium tin oxide, indium oxide, and tin oxide. The plating layer 22 itself has a high transmittance, which is advantageous for realizing the mirror surface effect. The main material of the electroplated layer 22 is a metal material with high resistance, so that the conductive substance is prevented from shielding the communication of the card data and affecting the performance of the smart card, and the use reliability of the smart card is improved.

In some embodiments, the thickness of the electroplated layer 22 is 0 mm-0.1 mm, and compared with the technical scheme that a glass mirror is embedded in the smart card, the thickness of the smart card can be greatly reduced by the scheme adopted in the embodiments of the present application, and the influence of the thickness of the mirror layer 2 on the hand feeling of the smart card is reduced. The electroplating process adopted by the application can reduce the thickness of the electroplated layer 22 to be less than 0.1mm, so that the overall thickness of the smart card meets the conventional standard thickness, and the method has strong universality.

While the application has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the application. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. The present application is not intended to be limited to the particular embodiments disclosed herein but is to cover all embodiments that may fall within the scope of the appended claims.
