[0041] Figure 3 In the middle, the circuit in the electromagnetic energy area of the card reader, the four-edge light-emitting smart card antenna 004 forms an alternating current, after rectification through the diode 006, forms a direct current, so as to light the side light-emitting LED lamp 005, the number of diode 006 here is not defined specifically can be increased according to the demand, the minimum requirement is 1.

[0042] Figure 4In the middle, the side light-emitting LED lamp 005 material can adopt PVC, RPVC, PETG, RPETG, PC, PET, etc., the thickness of the transparent film is configured according to the thickness requirement of the smart card INLAY, and the high-transmittance material is better selected, the back of the transparent film needs to be sprayed with a special low-temperature glue, which is convenient for bonding with the light guide sheet 009, the light guide sheet 009 adopts PC material with high light transmittance, and the thickness of the light guide sheet 009 is adjusted according to the thickness requirement of the finished card: according to the standard of 0.8±0.04 of the standard card, the thickness of the light guide sheet 009 is selected as (0.17*0.3) mm, for the super-thick non-standard card product, the thickness of the light guide sheet 009 is selected to be more than 0.3 mm, the thicker the thickness of the light guide sheet 009, the better the brightness and uniformity of the light guide of the light guide sheet 009, the back of the light guide sheet 009 needs to be treated according to the light irradiation condition, different density of light reflection points are set according to the principle of distance from the light source, which is convenient for balancing the brightness, the front of the light guide sheet 009 needs to be wound with the IC antenna 002, the light guide sheet 009 needs to be opened to avoid the position hole of the LED and the diode 006, to prevent the damage of the components during the laminating process, the size of the position hole is larger than the size of the components by about 1 mm, which will cause cracks or unevenness around the components, so a part of transparent glue needs to be filled at the component part to ensure the flatness of the component part, the LED upper layer 010 needs to adopt white material (PVC, PETG, PC, PET, etc.), and the white color can play a role of reflecting light. If the material cannot be selected as transparent material, white ink needs to be printed on the front to realize the reflecting effect, the thickness of the LED upper layer 010 is recommended to be 0.1 mm, the LED upper layer 010 needs to be opened to the circuit board positioning hole, which is convenient for fixing the position of the circuit board, because the thickness of the circuit board FPC is 0.06 mm, there is a certain height difference between the upper layer, which causes the concave situation of the circuit board, so a part of transparent glue needs to be filled at the circuit board, the front of the upper layer needs to be sprayed with cold temperature glue, which is convenient for bonding with the light guide sheet 009, the four-edge light-emitting smart card antenna 004 needs to be wound on the back of the upper layer to leave the conduction of the light guide sheet 009, to prevent the light back from blocking, the material of the four-edge light-emitting smart card antenna 004 is not limited, the front needs to be sprayed with low-temperature glue, which is convenient for bonding with the upper layer, and the thickness is adjusted according to the thickness requirement of the INLAY.

[0043] Figure 5In the middle, the INLAY material part is the same as above, the front and back of the INLAY need to be sprayed with low-temperature glue, which is convenient for bonding with the upper and lower printing layers. The back printing fabric 012 is not limited in material (PVC, PETG, PC, PET, etc.), which is adjusted according to the actual situation, and the material with good light shielding is preferred. If the material itself cannot shield the light well, the black silk screen needs to be printed on the back of the back printing fabric 012 to solve the problem of light leakage. The thickness of the back printing fabric 012 is not limited in material (PVC, PETG, PC, PET, etc.), and the material with good light transmittance is required. The thickness is as consistent as the back printing fabric 012 as much as possible, because the light source is placed in the center of the smart card. According to the scattering of light, two-thirds of the area of the smart card is illuminated, and the four-edge light-emitting product only highlights the edge of the smart card and the light emitted around the card. Therefore, the excess light needs to be shielded by the printing layer of the front printing fabric 013. The light shielding process requirement of the front printing fabric 013 is seen in Figure 7 A layer of white or silver is silk-screen printed on the front printing fabric 013, which is convenient for light emission. A layer of black is silk-screen printed for light shielding, and the light shielding part is limited according to the bright part. A layer of white is printed to facilitate subsequent printing of other colors. The front printing fabric 013 is provided with a glue film 014, which is not limited in material and is provided with a single-side low-temperature glue for bonding with the printing fabric. The thickness is adjusted according to the thickness requirement of the finished card. When the four-edge light-emitting smart card is laminated with low-temperature, the temperature requirement is selected as 80°-120°. According to the different temperature requirements, a special low-temperature glue is selected, and the low-temperature glue is coated between the layers to facilitate bonding under different temperature conditions.

[0044] Figure 8 In the middle, the standard smart card has four-edge light-emitting effect. The green part away from the edge of the smart card is the light-emitting area, and the light will leak from the side of the card. The middle black part needs to be shielded with black ink for light shielding. When the light-emitting smart card enters the electromagnetic energy area of the card reader, several LEDs will be lit. The LED light is transmitted to the surrounding through the light guide sheet 009, and the parts needing power will emit light uniformly.

[0045] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the technical field can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
