[0038] Please refer to Figure 1 and Figure 3 , Figure 1It is a schematic structural diagram of an intelligent card with an information anti-peeping function according to an embodiment of the present application; Figure 2 It is a schematic cross-sectional view of the first anti-peeping structure J1 according to an embodiment of the present application; Figure 3 It is an embodiment of the present application Figure 1 The cross-sectional view at A-A in it.

[0039] The embodiment of the present application provides an intelligent card with an information anti-peeping function, including: a card body 1, the card body 1 includes a first surface F1 and a second surface F2 oppositely arranged along the thickness direction of the intelligent card with an information anti-peeping function; an information identification part 2, a slot K is provided on one of the first surface F1 and the second surface F2, the information identification part 2 is located in the slot K, or the information identification part is fixed on one of the first surface F1, the second surface F2, and the inside of the card body; an anti-peeping layer 3, the anti-peeping layer 3 is located on the side of the information identification part 2 away from the card body 1, and the orthographic projection of the anti-peeping layer 3 on the card body 1 covers the orthographic projection of the information identification part 2 on the card body 1.

[0040] The intelligent card with an information anti-peeping function provided by the embodiment of the present application includes a card body 1, an information identification part 2, and an anti-peeping layer 3. After being covered by the anti-peeping layer 3, the two-dimensional code of the information identification part 2 can only be recognized by a code-sweeping device or a code-scanning gun at a very small angle of direct view, and cannot be directly observed or recognized outside the direct-viewing angle, so as to avoid being secretly photographed and stolen by irrelevant people around. And in the present application, a slot K can be set to accommodate the information identification part 2 and the anti-peeping layer 3 in the slot K, which can realize the anti-peeping function without affecting the thickness of the intelligent card with an information anti-peeping function, ensure that the thickness of the intelligent card with an information anti-peeping function meets the standard, facilitate the normal entry and exit of the intelligent card with an information anti-peeping function into an ATM or a POS machine, improve the user experience, and improve the use performance of the intelligent card with an information anti-peeping function.

[0041] In the prior art, since the PET anti-peeping layer still has a certain thickness, the thinnest PET anti-peeping film is about 0.3 mm at present. If the anti-peeping layer 3 is directly pasted on the card surface, it may cause the card thickness to exceed the standard, thus affecting the normal entry and exit of the card into an ATM or a POS machine. Therefore, in the present application, by setting the slot K, the anti-peeping layer 3 can be accommodated in the slot K, which can realize the anti-peeping function without affecting the thickness of the intelligent card with an information anti-peeping function, and ensure that the thickness of the intelligent card with an information anti-peeping function meets the standard.

[0042] In this embodiment, the card body 1 is used to carry the information identification part 2 and the anti-peeping layer 3, and the card body 1 can be prepared by using at least one of a polyvinyl chloride layer (PVC), a polyethylene terephthalate layer (PET), a polycarbonate layer (PC), and a polystyrene layer (PG).

[0043] Optionally, the information identification portion 2 includes a two-dimensional code identification portion, and the two-dimensional code identification portion may include a two-dimensional code formed by printing methods such as laser printing, ink printing or thermal offset printing.

[0044] A groove K is provided on one of the first surface F1 and the second surface F2, and the information identification part 2 is located in the groove K, or the information identification part 2 is fixed to one of the first surface F1, the second surface F2, and the inside of the card body 1, which means that the information identification part 2 can be located in the groove K, or located inside the card body 1 and arranged corresponding to the groove K so that the anti-peep layer 3 can cover the information identification part 2, or the card body 1 may not be provided with the groove K, and the information identification part 2 is directly fixed to the first surface F1 or the second surface F2.

[0045] It should be noted that the orthographic projection of the anti-peeping layer 3 on the card body 1 covers the orthographic projection of the information identification part 2 on the card body 1, that is, the size and area of ​​the anti-peeping layer 3 can be greater than or equal to the size and area of ​​the information identification part 2, as long as the anti-peeping layer 3 can completely cover the information identification part 2.

[0046] See also Figure 2 and Figure 3 In some optional embodiments, the smart card with information anti-peeping function includes a first anti-peeping structure J1, and the first anti-peeping structure J1 includes a first adhesive layer 6, a base layer 5, an anti-peeping layer 3 and a hardened protective layer 4 stacked along the thickness direction of the smart card with information anti-peeping function. The first anti-peeping structure J1 is located in the groove K.

[0047] In this embodiment, the hardened protective layer 4 can be OCA (Optically Clear Adhesive), which mainly protects the anti-peeping layer 3. The anti-peeping layer 3 can adopt an ultra-fine blinds structure, and the offset angle of the blinds determines the range of the input viewing angle that can be accurately identified. The base layer 5 can be made of PET material to support the anti-peeping layer 3. The first adhesive layer 6 can be a double-sided adhesive layer, which is used to bond the first anti-peeping structure J1 and the card body 1.

[0048] Optionally, when the first anti-peeping structure J1 is not fixed in the groove K, a PET release layer 7 can be set on the side of the first adhesive layer 6 facing away from the base layer 5 and on the side of the hardened protective layer 4 facing away from the base layer 5 to physically protect the anti-peeping layer 3 and prevent the anti-peeping layer 3 from being scratched or adsorbing dirt. When used on a smart card with information anti-peeping function, both the upper and lower release layers 7 need to be removed.

[0049] See also Figure 2 and Figure 3, in some alternative embodiments, along the thickness direction of the smart card with information anti-peeping function, the card body 1 includes a first protective layer 11, a first printed substrate layer 12, a two-dimensional code compensation layer 13, an antenna layer 14, a second printed substrate layer 15, and a second protective layer 16 which are stacked; the slot K is opened in the first protective layer 11 and extends at least to the first printed substrate layer 12, or the slot K is opened in the second protective layer 16 and extends at least to the second printed substrate layer 15; the information identification portion 2 is disposed on the surface of the two-dimensional code compensation layer 13 facing away from the antenna layer 14.

[0050] In this embodiment, the first protective layer 11 is used to protect the first printed substrate layer 12 and prevent the patterns on the first printed substrate layer 12 from being damaged. In this embodiment, the depth of the slot K should not be too deep, that is, the slot K preferably does not penetrate the first printed substrate layer 12 to avoid damaging the two-dimensional code pattern on the information identification portion 2. Additionally, the depth of the slot K cannot be too shallow either. The depth of the slot K must penetrate the first protective layer 11 and enter the first printed substrate layer 12 to allow the anti-peeping layer 3 to sink into the card body 1 as much as possible.

[0051] The information identification portion 2 can be printed on the two-dimensional code compensation substrate. Both the first protective layer 11 and the first printed substrate layer 12 can be made of transparent materials to ensure the visibility of the two-dimensional code pattern.

[0052] Optionally, the antenna layer 14 includes a chip 141 and a coil 142 electrically connected to the chip 141. The coil 142 is arranged in a ring shape, specifically, it can be arranged in a square or circular shape. The coil 142 is used to provide energy for the chip 141 module.

[0053] Optionally, the chip 141 is close to the magnetic field of the card reader, and it is required that the induced current generated by the coil 142 can supply non-contact communication. The larger the circumferential area of the coil 142, the larger the induced current generated by the coil 142.

[0054] In this embodiment, the slot K can be opened in the first protective layer 11 or the second protective layer 16, that is, on one side of the first surface F1 or the second surface F2 of the smart card with information anti-peeping function.

[0055] Please refer to Figure 2 and Figure 3 , in some alternative embodiments, the first anti-peeping structure J1 is bonded to the first printed substrate layer 12 through the first adhesive layer 6. That is, there is still a first printed substrate layer 12 between the first anti-peeping structure J1 and the information identification portion 2. This part of the first printed substrate layer 12 needs to be made of transparent material to avoid affecting the visibility of the two-dimensional code in the information identification portion 2.

[0056] Optionally, along the thickness direction of the smart card with an information anti-peeping function, the depth of the slot K is greater than or equal to the thickness of the first anti-peeping structure J1, so that the slot K can completely accommodate the first anti-peeping structure J1, avoiding the first anti-peeping structure J1 protruding out relative to the card body 1 and ensuring the normal use of the smart card with an information anti-peeping function.

[0057] Please refer to Figure 2 and Figure 3 , in some alternative embodiments, the slot K is formed in the first protective layer 11 and extends at least to the first printed substrate layer 12. The first printed substrate layer 12 includes a transparent material, and at least a part of the second printed substrate layer 15 corresponding to the two-dimensional code compensation layer 13 is provided with light shielding.

[0058] In this embodiment, since the slot K is formed in the first protective layer 11 and extends at least to the first printed substrate layer 12, and the first anti-peeping structure J1 is also correspondingly arranged in the slot K, therefore, there may also be a first printed substrate layer 12 between the first anti-peeping structure J1 and the information identification part 2. The first printed substrate layer 12 can be prepared from a transparent material to avoid affecting the visibility of the two-dimensional code in the information identification part 2. And at least a part of the second printed substrate layer 15 corresponding to the two-dimensional code compensation layer 13 is provided with light shielding, that is, at least this part of the second printed substrate layer 15 cannot be transparent, otherwise the two-dimensional code may be seen through. The second printed substrate layer 15 can be prepared using a white or black PVC substrate, or the entire part of the second printed substrate layer 15 can be covered by a screen printing process.

[0059] Among them, at least a part of the second printed substrate layer 15 corresponding to the two-dimensional code compensation layer 13 can be understood as the part of the second printed substrate layer 15 that overlaps with the information identification part 2 along the thickness direction of the smart card with an information anti-peeping function.

[0060] Please refer to Figure 4 and Figure 5 , in some alternative embodiments, the smart card with an information anti-peeping function includes a second anti-peeping structure J2. The second anti-peeping structure J2 includes a second adhesive layer 8, an information identification part 2, and an anti-peeping layer 3 that are stacked along the thickness direction of the smart card with an information anti-peeping function. The second anti-peeping structure J2 is located in the slot K.

[0061] In this embodiment, the transaction two-dimensional code can be printed on a large substrate first, and then the two-dimensional code on the large substrate is punched out along the two-dimensional code contour to obtain a single-piece two-dimensional code, that is, the information identification part 2. Then, the anti-peeping layer 3 is pre-compounded with the information identification part 2, and then the composite structure is back-glued to form the second anti-peeping structure J2. Finally, the second anti-peeping structure J2 is fixed in the slot K.

[0062] The second adhesive layer 8 can specifically adopt a double-sided adhesive layer.

[0063] Optionally, a release layer 7 may be provided on the side of the adhesive layer facing away from the information identification portion 2 and on the side of the anti-peeping layer 3 facing away from the information identification portion 2 to protect the adhesive layer and the anti-peeping layer 3, and the release layer 7 is removed when it is fixed to the slot K.

[0064] Please refer to Figure 4 and Figure 5 , in some alternative embodiments, along the thickness direction of the smart card with information anti-peeping function, the card body 1 includes a first protective layer 11, a first printed substrate layer 12, an antenna layer 14, a second printed substrate layer 15, and a second protective layer 16 that are stacked; the slot K is formed in the first protective layer 11 and extends at least to the first printed substrate layer 12.

[0065] In this embodiment, the smart card with information anti-peeping function does not need to add an extra film layer, that is, the overall thickness of the smart card with information anti-peeping function will not be affected. Only the slot K needs to be formed in the first protective layer 11 and extend at least to the first printed substrate layer 12 to accommodate the second anti-peeping structure J2, so as to achieve the anti-peeping function for the two-dimensional code.

[0066] Please refer to Figure 7 , in some alternative embodiments, the orthographic projections of the chip 141 and the coil 142 of the antenna layer 14 on the first protective layer 11 do not coincide with the orthographic projection of the slot K on the first protective layer 11, so as to avoid interference between the chip 141, the coil 142 and the film layers such as the anti-peeping layer 3 or the information identification portion 2 located in the slot K.

[0067] Optionally, the smart card with information anti-peeping function further includes a card element carrier portion B provided on the surface of the second protective layer 16 facing away from the second printed substrate layer 15, and the orthographic projection of the card element carrier portion B on the first protective layer 11 does not coincide with the orthographic projection of the slot K on the first protective layer 11, so as to avoid interference between the card element carrier portion B and the film layers such as the anti-peeping layer 3 or the information identification portion 2 located in the slot K.

[0068] Please refer to Figure 8 and Figure 9 , in some alternative embodiments, along the thickness direction of the smart card with information anti-peeping function, the card body 1 includes a first protective layer 11, a first printed substrate layer 12, an antenna layer 14, a second printed substrate layer 15, and a second protective layer 16 that are stacked; the slot K is formed in the first protective layer 11 and penetrates through the first printed substrate layer 12; in the direction of the antenna layer 14 facing away from the second printed substrate layer 15, an information identification portion 2 formed by laser marking, a third adhesive layer 9, and an anti-peeping layer 3 are sequentially provided in the slot K.

[0069] After the slot is formed by milling or other methods, the information identification part such as the transaction QR code is etched in the slot by laser coding, and then the anti-peep layer consistent with the milling slot shape is mounted in the reserved slot. When milling the slot, a fine path must be set for milling, and the bottom must be smooth and flat after milling, and the knife marks and burrs at the bottom of the slot during the milling process must be minimized. Only when the bottom of the slot is smooth enough will the QR code bar not be deformed and affect recognition after the subsequent laser printing of the QR code; the laser QR code must be printed in the slot. Generally speaking, the size of the slot should be appropriately enlarged considering the tolerance of the processing process. When laser processing the QR code image, it is also necessary to pay attention to controlling the laser energy and position so that the QR code is clearly identifiable in the bottom slot and has a color contrast with the bottom background color; the milling slot position of the QR code should also avoid the setting area of ​​the coil and the card element carrier part B.

[0070] See also Figure 10 In some optional embodiments, one of the first surface F1 and the second surface F2 is provided with a protruding frame structure N; on the one of the first surface F1 and the second surface F2 provided with the frame structure N, an information identification portion 2 formed by thermal lithography, a fourth adhesive layer J provided on the side of the information identification portion 2 facing away from the card body 1, and an anti-peep layer 3 are provided in the area enclosed by the frame structure N.

[0071] In this embodiment, the information identification part 2, such as a transaction QR code, can be printed on the surface of the card body 1 by thermal printing on the card body 1, and then a 3D printing process is used to print a border around the QR code to form a border structure N. The size of the 3D printed border is larger than the size of the QR code, and the height of the 3D printed border is close to the thickness of the anti-peeping layer 3. Then, an anti-peeping layer 3 patch with the same size as the border structure N is designed, and finally the anti-peeping layer 3 patch is mounted in the border structure N.

[0072] This solution is completely processed on the card surface without additional milling. There is no specific requirement for the position of the coil of the card body 1, but the height of the anti-peeping layer 3 processed on the card surface needs to be considered to avoid the anti-peeping layer 3 exceeding the thickness limit and causing difficulty in inserting the card into the ATM machine. Generally speaking, the height of the element protruding from the card surface is not greater than the height of the conventional embossed characters, that is, the anti-peeping layer 3 on the card surface shall not exceed 0.46mm; in addition, the frame structure N mainly protects and positions the anti-peeping layer 3, which can prevent the anti-peeping layer 3 from being torn from the edge by hand to a certain extent, and plays a positioning role in the process of mounting the anti-peeping layer 3.

[0073] See also Figure 6 Optionally, the slot K may extend to the second printed substrate layer 15 as long as the chip 141 and the coil 142 of the antenna layer 14 are avoided.

[0074] See also Figure 7, in some alternative embodiments, the card element carrier portion B includes at least one of a magnetic stripe, an anti-counterfeiting mark, and a signature strip. Specific selection needs to be made according to specific requirements.
