[0024] Reference Figure 1The anti-counterfeiting card 10 provided in this embodiment includes a first substrate layer 3, an intermediate layer 1, and a second substrate layer 2 stacked sequentially from top to bottom. A first printing layer 4 is disposed on the side of the first substrate layer 3 opposite to the intermediate layer 1, and a second printing layer 5 is disposed on the side of the second substrate layer 2 opposite to the intermediate layer 1. The card is provided with a mounting hole 9, which passes sequentially through the first printing layer 4, the first substrate layer 3, the intermediate layer 1, the second substrate layer 2, and the second printing layer 5. The top and bottom of the mounting hole 9 are both open. A colored film 8 with silver halide photosensitive emulsion is disposed in the mounting hole 9. An anti-counterfeiting image is disposed on the colored film 8. The anti-counterfeiting image includes at least one of the following: numbers, personal signature, portrait, and pattern. Preferably, the first substrate layer 3 is made of one of the following materials: polyvinyl chloride, polyester, polyethylene terephthalate, resin, and polycarbonate. The second substrate layer 2 is made of one of the following materials: polyvinyl chloride, polyester, polyethylene terephthalate, resin, and polycarbonate. The first printing layer 4 contains at least one of the following: a signature strip, a hologram, intaglio text, a barcode, a QR code, and personal signature information. The second printing layer 5 contains at least one of the following: a signature strip, a hologram, intaglio text, a barcode, a QR code, and personal signature information.

[0025] Optionally, only the first printing layer 4 can be set, that is, the second printing layer 5 can be omitted.

[0026] In this embodiment, a transparent first protective layer 6 is provided on the side of the first printed layer 4 facing away from the first substrate layer 3, and a transparent second protective layer 7 is provided on the side of the second printed layer 5 facing away from the second substrate layer 2. The first protective layer 6 and the second protective layer 7 respectively cover the opposite sides of the color film 8. The first protective layer 6 and the second protective layer 7 can be transparent plastic films or transparent coatings, etc.

[0027] Optionally, the card also includes an electrically connected chip (not shown in the figure) and a communication coil (not shown in the figure), with the chip located on the card and the communication coil located on the intermediate layer 1, giving the anti-counterfeiting card more functions.

[0028] The manufacturing method of the anti-counterfeiting card 10 in this embodiment includes the following steps: See Figure 2 A first printing layer 4 is disposed on the side of the first substrate layer 3 opposite to the intermediate layer 1, and a second printing layer 5 is disposed on the side of the second substrate layer 2 opposite to the intermediate layer 1. Mounting holes 9 are formed on the card body, passing through the first substrate layer 3, the second substrate layer 2, and the intermediate layer 1. A color film 11 with an anti-exposure seal (not shown in the figure) is installed into the mounting hole 9 and integrated with the first substrate layer 3, the second substrate layer 2, and the intermediate layer 1. The anti-exposure seal completely covers the opposite surfaces of the color film.

[0029] Next, imaging needs to be performed on the color film 11 on the anti-counterfeiting card 10. Before imaging, the anti-exposure seal on the anti-counterfeiting film is removed. During imaging, the image light 23 reflected from the anti-counterfeiting image 21 is focused onto the color film 11 by the focusing device 22. The color film 11 records the anti-counterfeiting image 21. The color film 11 with the anti-counterfeiting image 21 is then developed, so that the anti-counterfeiting image 21 is fixed on the color film 11 to form a color negative. Preferably, the color film 11 on the anti-counterfeiting card 10 is imaged and developed in a dark environment. Finally, a first protective layer 6 is provided on the side of the first printing layer 4 opposite to the first substrate layer 3, and a second protective layer 7 is provided on the side of the second printing layer 5 opposite to the second substrate layer 2.

[0030] The verification method for the anti-counterfeiting card 10 in this embodiment includes the following steps: See Figure 3 The light beam emitted by the light source 31 is focused by the focusing device 32. The light beam passes through the color film 8 to form an image light 33 with an anti-counterfeiting image. The image light 33 is magnified by the objective lens 35 and projected onto the screen 34. The inspector checks the anti-counterfeiting image 36 on the screen 34.

[0031] As can be seen, the anti-counterfeiting card of the present invention has good anti-counterfeiting effect, is convenient to produce and manufacture, and is easy to verify and observe.

[0032] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
