Problems solved by technology

[0002] In the process of barcode application, usually, it is only expressed through a layer of image symbol information, which is a flat piece of information. For barcode symbols, this not only limits the content of barcode storage, but also cannot effectively resist specific Possibility of obtaining barcode symbol information

Embodiment 1

[0028] Such as figure 1 As shown, in the process of making and identifying ultraviolet barcodes, a piece of information is printed on the face of the bill with ultraviolet ink. After drying, a red barcode is printed on the position of the invisible barcode and pasted on the carrier. . The ultraviolet light source emits ultraviolet light to the surface of the barcode, which excites the ultraviolet ink to emit visible light to the reading machine. After the reading machine receives the light, it filters the ultraviolet light through the polarized light interception technology, and enters the available light into the sensor of the reading machine for imaging and decoding. , read out the barcode information. Synchronously, through the control of the background software, the reader starts another reading method. After identifying the barcode on the surface, the two pieces of information are verified by the algorithm. After the verification is correct, it indicates the authenticity...

Abstract

The invention relates to a multiband three-dimensional bar code as well as a manufacturing method and application thereof. The three-dimensional bar code comprises two layers of bar codes, the two layers of bar codes are respectively of a bar code with visible ink printing and of a bar code of multiband ink printing, and the bar code with visible ink printing is arranged above the bar code of the multiband ink printing. Compared with the prior art, the bar code has the following advantages that: a novel anti-counterfeit method is added, and the social data safety ensuring capacity is improved; being combined with a two-dimensional bar code, the anti-counterfeit capacity of the data which can not be identified by eye can be increased; being combined with the car code, the data processing speed and data processing capacity are strengthened, and the application efficiency and accuracy are improved; the anti-counterfeit technology with low cost is realized, so the bar code is easy to be widely used; through the bar code information of different layers, the storage content and information volume of the bar code can be increased; through the bar code information of different layers, association is performed, so the safety of the storage content of the bar code is improved; and since different light source systems are required, the cracking difficulty is increased.

Description

technical field [0001] The invention relates to the fields of information technology and automatic identification technology, in particular to a multi-band three-dimensional barcode and its manufacturing method and application. Background technique [0002] In the process of barcode application, usually, it is only expressed through a layer of image symbol information, which is a flat piece of information. For barcode symbols, this not only limits the content of barcode storage, but also cannot effectively resist specific Possibility of barcode symbol information being captured. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the above-mentioned prior art, and provide a multi-band three-dimensional barcode that can be used for anti-counterfeiting, its manufacturing method and application. [0004] The purpose of the present invention can be achieved through the following technical solutions: a multi-band three-dimensio...
