Two-dimensional barcode coding device and decoding device

The present invention provides a two-dimensional barcode encoding apparatus and decoding apparatus, and more particularly to an encoding apparatus and a decoding apparatus that encode at least one one-dimensional barcode feature into a two-dimensional barcode.

One-dimensional bar code is an electronic bar code technology, which has the advantages of fast input information, fast reading speed and high reliability. Generally, one-dimensional barcodes are often introduced into the relevant identification system to improve work efficiency. At present, the encoding methods of common one-dimensional barcodes include Code39 code, Codabar code, Code 25 code, ITF 25 code, Matrix 25 code, UPC-A code, UPC-E code, EAN-13 code EAN-8 code, Code-B. Code, MSI code, Code 11 code, Code 128 code, ISBN code, ISSN code, etc. Although there are many types of one-dimensional barcodes, since the length of the characters on the barcode cannot usually exceed 15, the information accessed is limited to indicating an object, and the object itself cannot be described in detail. Therefore, it must be used first. Connect to the Internet and related databases.

Two-dimensional bar code is another electronic bar code technology, which is mainly used in automated text transmission, digital content URL link download, URL quick link, identity authentication and business transaction. Although the 2D barcode can carry more information, it still has a limitation on the data capacity. At present, the coding methods of common two-dimensional barcodes include QR code, PDF 417 code, Data Matrix code, and the like. Although the 2D barcode can carry more information, it still has a limitation on the data capacity. In the case of a QR code, the number can be up to 7,089 characters, letters up to 4,296 characters, and binary digits (8 bits) up to 2,953 bytes. The more the amount of data encoded by the two-dimensional bar code, the more the file size will increase, it is not conducive to Optical identification decoding of 2D barcodes. In addition, the conventional 2D barcode decoding method is 1) using an optical capture device (such as a CCD image capture device or a CMOS image capture device) to capture a 2D barcode image, and then 2) obtaining a 2D image through the decoding software. The barcode, and finally 3) decode the obtained 2D barcode and display the result.

Therefore, how to carry various types of information under the limited data capacity of the two-dimensional barcode, without causing the file to be too large and affecting the optical identification and decoding capability, will facilitate the carrying of more data in the two-dimensional barcode. In addition, in the process of reading the two-dimensional barcode, if the image of the two-dimensional barcode can be obtained without the optical pickup device, the time for decoding the two-dimensional barcode can be accelerated.

The present embodiment provides a two-dimensional barcode encoding apparatus for encoding at least one one-dimensional barcode feature into a two-dimensional barcode. The one-dimensional bar code has a plurality of black bars and a plurality of white bars arranged in parallel. The encoding device includes a storage component, a first transfer component, and a processor. The first transfer element is electrically connected to the storage element. The processor is electrically connected to the first transmission component, obtains a one-dimensional barcode through the first transmission component, and horizontally captures one horizontal image of the one-dimensional barcode and compresses the horizontal image at a position adjacent to a horizontal center line of the one-dimensional barcode. A ciphertext information is formed accordingly, and the horizontal image has a portion of each black strip and a portion of each white strip. And the processor encodes the ciphertext information into a two-dimensional barcode to generate an image of the two-dimensional barcode, and stores the image of the two-dimensional barcode to the storage component.

The present invention provides a two-dimensional barcode decoding apparatus for acquiring at least one one-dimensional barcode feature in a two-dimensional barcode image. The one-dimensional bar code has a plurality of black bars and a plurality of white bars arranged in parallel. The decoding device includes a second transfer component and an arithmetic processing component. The operation processing component is electrically connected to the second transmission component, obtains an image of the two-dimensional barcode through the second transmission component, and decodes the image of the two-dimensional barcode to generate a ciphertext information. Ciphertext information has a horizontal image of one of the compressed one-dimensional barcodes. The horizontal image is captured horizontally at a position adjacent to a horizontal centerline of one of the one-dimensional barcodes, and The horizontal image has a portion of each black strip and a portion of each white strip. And the operation processing component decompresses the ciphertext information to generate a horizontal image of the one-dimensional barcode, and longitudinally expands the horizontal image by a code height to generate an image representing the one-dimensional barcode.

In summary, the present embodiment provides a two-dimensional barcode encoding apparatus and decoding apparatus, which can compress and encode at least one image of a one-dimensional barcode feature (such as the horizontal image) into a two-dimensional barcode, and simultaneously Coding one or a combination of text information and digital information into a two-dimensional bar code, so that the image file of the two-dimensional bar code is not too large, and does not affect the optical identification decoding capability, and can not be optically captured, in one time. The transmission carries more one-dimensional bar code features and has a smaller file, so that the object itself can be described in more detail. Since the file of the two-dimensional barcode is small, the encoding device can quickly transmit the image of the two-dimensional barcode to the decoding device to further decode the two-dimensional barcode to generate an image representing the one-dimensional barcode, and the text information and the digital information. One or a combination thereof.

In the following, the present creation will be described in detail by way of various illustrative embodiments of the present invention. However, the inventive concept may be embodied in many different forms and should not be construed as being limited to the illustrative embodiments set forth herein. In addition, the same reference numerals may be used in the drawings to represent similar elements.

The present embodiment provides a two-dimensional barcode encoding apparatus and decoding apparatus. In the encoding process, the encoding device obtains a one-dimensional barcode, and extracts a horizontal image of the one-dimensional barcode as a one-dimensional barcode feature, and compresses the one-dimensional barcode feature, and encodes one of the text information and the digital information or a combination thereof. For 2D barcodes. In the decoding process, the decoding device first decodes the image of the two-dimensional barcode into a compressed one-dimensional barcode feature, and one or a combination of the text information and the digital information; and then decompresses the compressed one-dimensional barcode feature. A horizontal image representing a one-dimensional bar code and longitudinally extending a horizontal image representing a one-dimensional bar code to a predetermined height to generate a one-dimensional bar code image. Accordingly, the image file of the two-dimensional barcode of the present embodiment is not too large and will not be affected. The optical identification and decoding capability can carry more detailed one-dimensional barcode features and have smaller files in one-time transmission without optical transmission, thereby providing more detailed information description of the object itself. Since the file of the two-dimensional barcode is small, the encoding device can quickly transmit the image of the two-dimensional barcode to the decoding device to further decode the image of the two-dimensional barcode to generate a one-dimensional barcode image. The encoding device and decoding device of the two-dimensional barcode disclosed in the present application will be further described below.

First, please refer to FIG. 1, which shows a schematic diagram of a two-dimensional barcode encoding apparatus according to an embodiment of the present invention. As shown in FIG. 1, the encoding device 100 is configured to encode at least one one-dimensional barcode feature into a two-dimensional barcode. Furthermore, the one-dimensional bar code is composed of a plurality of black bars and a plurality of white bars arranged in parallel, and the plurality of black bars and the plurality of white bars have different degrees of thickness according to different one-dimensional bar code encoding rules. The encoding device 100 encodes the feature relationship between the plurality of black bars and the plurality of white bars and the features related to the one-dimensional bar code into a two-dimensional bar code.

Taking the one-dimensional barcode code 39 as an example, please refer to FIG. 2A at the same time, one character is composed of 5 black bars and 4 white bars, and a total of 9 lines. Three of the nine lines are thick lines and six are thin lines. The thick lines are indicated as "1" and the thin lines are indicated as "0". Therefore, as shown in FIG. 2A, if the character "A" is to be represented in the one-dimensional bar code, the black bar portion will be represented by "10001", and the white bar portion will be represented by "0010". However, those skilled in the art should know the encoding rules of the complete one-dimensional barcode code 39, and therefore will not be described herein. In this embodiment, the encoding device 100 can be a server with a transmission function, such as a base station host, a machine (such as a POS machine, a multimedia guide (KIOSK)), and a mobile device (such as a mobile phone, a tablet, and a wearable device). The device or a combination of various electronic devices is not limited in this creation.

Referring back to FIG. 1 , the encoding device 100 includes a first transfer component 110 , a storage component 130 , and a processor 140 . In this embodiment, the one-dimensional barcode may be stored in the storage component 130 of the electronic device 100 or transmitted to the encoding device 100 by an external device.

Referring to FIG. 1 and FIG. 2B simultaneously, the first transfer component 110 is electrically connected to the storage component. 130 and obtain a one-dimensional barcode 1D. In the present embodiment, the first transfer component 110 is a one-dimensional barcode 1D obtained by an external device. The first transmission component 110 can also obtain the one-dimensional barcode 1D from the storage component 130, which is not limited in this creation. As shown in FIG. 2B, the one-dimensional barcode 1D has a certain ratio of the barcode length L and the barcode height H. It should be noted that FIG. 2B only expresses the relationship between the plurality of black bars Lb of the one-dimensional bar code 1D and the plurality of white bars Lw. Therefore, the present invention does not limit the one-dimensional bar code 1D of FIG. 2B.

The processor 140 is electrically connected to the first transfer component 110, and obtains the one-dimensional barcode 1D through the first transfer component 110 to encode the thickness relationship between the plurality of black bars and the plurality of white bars in the one-dimensional barcode 1D into two dimensions. Bar code.

As shown in FIG. 2B, the processor 140 horizontally captures one horizontal image Im of the one-dimensional barcode 1D at a position adjacent to one of the horizontal center lines Lc of the one-dimensional barcode 1D. The horizontal image Im has a portion of each black strip Lb and a portion of each white strip Lw. Furthermore, since the structure of the one-dimensional bar code 1D is a plurality of black bars Lb and a plurality of white bars Lw arranged in parallel, the horizontal image Im will represent a one-dimensional bar code 1D feature, so that the processor 140 can obtain the horizontal image Im. Knowing the thickness relationship between each black strip Lb and each white strip Lw (ie, the image of each black strip Lb spacing, or the image of each white strip Lw spacing), and then can be resolved after the decoding process of this patent One-dimensional bar code 1D information content.

After the processor 140 obtains the horizontal image Im, the processor 140 compresses the horizontal image Im to form a ciphertext information, thereby reducing the file size of the horizontal image Im. In this embodiment, the horizontal image Im is compressed by a run-length encoding (RLE) method to form ciphertext information, so that the compressed horizontal image Im is not distorted. The method for encoding the length of the run length is an image compression method generally used. Those skilled in the art should know the implementation and operation mode of the run length coding method, and therefore will not be described herein. Of course, the horizontal image Im can also be compressed by other lossless image compression methods (such as Huffman compression, Flate/deflate compression, LZW compression), or lossy image compression methods (such as JPEG compression), which is not limited in this creation.

In addition, after the ciphertext information is formed, the processor 140 can encrypt the ciphertext information through an RSA algorithm, so that the ciphertext information is not easily decoded by the interested person in the decoding process to obtain important data in the ciphertext information. The RSA algorithm is an encryption method generally used, and those skilled in the art should know the implementation and operation mode of the encryption method, and therefore will not be described here. Of course, ciphertext information can also be encrypted by other encryption algorithms. This creation does not limit this.

Next, the processor 140 encodes the ciphertext information into a two-dimensional barcode to generate an image of the two-dimensional barcode. Furthermore, the ciphertext information has an image start code and an image end code. Therefore, the processor 140 encodes the ciphertext information through a two-dimensional array data structure algorithm according to the image start code and the image end code, and generates a two-dimensional barcode image carrying the ciphertext information. The two-dimensional array data structure algorithm is a data structure method generally used, and those skilled in the art should know the implementation and operation mode of the data structure mode, and therefore will not be described here. Of course, ciphertext information can also be calculated by other data structure algorithms. This creation does not limit this.

For example, the one-dimensional barcode 1D is the invoice barcode of the "XX invoice", and the ciphertext information is the horizontal image Im of the compressed invoice barcode. Therefore, the processor 140 encodes the compressed horizontal image Im (ie, ciphertext information) into a two-dimensional barcode to generate an image of the two-dimensional barcode carrying the compressed horizontal image Im, as shown in FIG. 3A. Image d1.

After the processor 140 performs the encoding of the two-dimensional barcode in the ciphertext information, the processor 140 may additionally superimpose at least one identification image on at least one specific position of the image of the two-dimensional barcode (such as the image d1 in FIG. 3A). The user who receives the 2D barcode can intuitively understand the information usage of the 2D barcode from the image of the 2D barcode. It is worth noting that since the superimposed identification image actually represents the damaging part of the two-dimensional barcode, and if the damaged part of the two-dimensional barcode exceeds a predetermined ratio of the two-dimensional barcode (ie, the fault tolerance of the two-dimensional barcode), The image is reduced to true ciphertext information through the decoding mechanism, so the above-mentioned identification image needs to be smaller than a predetermined ratio of the two-dimensional barcode image. And more Good place, the scheduled ratio is 30%. Therefore, if the above-mentioned identification image is less than 30% of the image of the two-dimensional barcode, the two-dimensional barcode can be restored to the true ciphertext information through the decoding mechanism.

In other embodiments, the processor 140 may additionally obtain one or a combination of a text message and a digital message as a plaintext message, and encode the ciphertext information and the plaintext information by two-dimensional bar code to generate a two-dimensional code. Bar code image. Furthermore, the ciphertext information has an image start code and an image end code. The text message has a text start code and a text end code. The digital information has a digital start code and a digital end code. Therefore, the processor 140 can calculate the ciphertext information and the plaintext information according to the image start code, the image end code, the text start code, the text end code, the digital start code, and the digital end code through a two-dimensional array data structure. The method performs encoding of a two-dimensional barcode to generate an image of a two-dimensional barcode carrying ciphertext information and plaintext information. The two-dimensional array data structure algorithm is a data structure method generally used, and those skilled in the art should know the implementation and operation mode of the data structure mode, and therefore will not be described here. Of course, ciphertext information and plaintext information can also be implemented by other data structure algorithms. This creation does not limit this.

Similarly, the image d1 of FIG. 3A is used as an example. The one-dimensional barcode 1D is the invoice barcode of the “XX invoice”, and the ciphertext information is the horizontal image Im of the compressed invoice barcode. The plaintext information is a combination of the text information "August Invoice" and the digital information "12345678" (not shown in the figure). Therefore, the processor 140 encodes the compressed horizontal image Im (ie, ciphertext information), the text information "August invoice" (ie, plaintext information), and the digital information "12345678" (ie, plaintext information) into a two-dimensional barcode. The image of the two-dimensional barcode carrying the compressed horizontal image Im, the text information "August invoice" and the digital information "12345678" is generated.

As shown in FIG. 3A-3B, an exploded view and a schematic diagram of an image in which the identification image of the present embodiment is superimposed on the two-dimensional barcode is displayed. The image d1 of the two-dimensional barcode carries the compressed horizontal image Im, the text information "August invoice" and the digital information "12345678". The image in which the image d2 is "XX invoice" is recognized, and the image in which the image d3 is "8" is recognized. Therefore, the processor 140 will recognize the image d2 and D3 is superimposed on the specific positions Q1 and Q2 of the image d1 of the two-dimensional barcode, so that the images of the "XX invoice" and "8" are displayed on the image of the two-dimensional barcode. However, those skilled in the art should be aware of the implementation and operation of the image in which the image is superimposed on the two-dimensional barcode, and therefore will not be described herein. Of course, the recognition image can also be used for other image synthesis algorithms, and this creation does not limit this.

Referring to FIG. 1 at the same time, after generating the image of the two-dimensional barcode, the processor 140 transmits the image of the two-dimensional barcode to a decoding device (such as the decoding device 200 of FIG. 4) through a transmission manner. At this time, the user of the handheld decoding device can visually see the image of the "XX invoice" and the "8" superimposed on the image of the two-dimensional barcode on the screen, so as to know that the two-dimensional barcode is "8". The XX invoice for the month, and the decoding device can decode the image of the 2D barcode to restore the information of the real one-dimensional barcode, the text information "August invoice" and the digital information "12345678". In this embodiment, the decoding device may be a device having a transmission function, such as a smart phone, a tablet computer, a wearable device, or a wireless communication transmission module having a telecommunication communication module or a network communication module, such as POS machines, multimedia guides (KIOSK), or a combination of various electronic devices, this creation does not limit this.

The above transmission methods may be asymmetric digital subscriber loop (ADSL) transmission, cable television network transmission, optical fiber transmission, Bluetooth transmission, near field communication (NFC) transmission, multimedia messaging (MMS) transmission, instant messaging ( IM) transmission, infrared transmission, IEEE802.11 transmission, GSM transmission, GPRS transmission, Internet or 3G/4G mobile communication network, this creation does not limit this.

It can be seen from the above that in the encoding process, the encoding device obtains the one-dimensional barcode, and then captures and compresses the horizontal image of the one-dimensional barcode to encode the two-dimensional barcode, so that the image file of the two-dimensional barcode is not too large or affected. The optical identification decoding capability can carry more one-dimensional bar code features and have smaller files in one-time transmission, so that more detailed information description can be performed on the object itself. Since the file of the two-dimensional barcode is small, the encoding device can quickly transmit the image of the two-dimensional barcode to the decoding device to further decode the two-dimensional barcode to generate an image representing the one-dimensional barcode. this In addition, during the encoding process, the encoding device may also encode one or a combination of text information and digital information and the compressed horizontal image into a two-dimensional barcode, and transmit the image of the two-dimensional barcode to the decoding device. The decoding device further decodes the two-dimensional barcode to generate an image representing the one-dimensional barcode, and information of one or a combination of the text information and the digital information.

Next, please refer to FIG. 1 and FIG. 4 at the same time, and FIG. 4 shows a schematic diagram of a decoding device for a two-dimensional barcode according to an embodiment of the present invention. The decoding device 200 is configured to obtain at least one-dimensional barcode feature in the image of the two-dimensional barcode. Furthermore, the one-dimensional bar code is composed of a plurality of black bars and a plurality of white bars arranged in parallel, and the plurality of black bars and the plurality of white bars have different degrees of thickness relationship according to different one-dimensional bar code encoding rules.

The decoding device 200 includes an arithmetic processing component 210 and a second transfer component 220. The second transfer component 220 is an image for obtaining a two-dimensional barcode. In this embodiment, the second transfer component 220 is an image d1 of a two-dimensional barcode obtained by an external device (such as the encoding device 100) or an image d1 of a two-dimensional barcode that is previously stored in the decoding device 200. No restrictions. For convenience of explanation, the decoding device 200 will be described below by receiving the image d1 of the two-dimensional barcode transmitted by the encoding device 100.

The arithmetic processing unit 210 is electrically connected to the second transfer element 220, and obtains the image d1 of the two-dimensional barcode transmitted by the encoding device 100 through the second transfer element 220. It should be noted that the decoding device 200 further includes a display component 230. Display component 230 is electrically coupled to operational processing component 210 and has a decoding interface 235. Before the operation processing component 210 decodes the image d1 of the two-dimensional barcode, the display component 230 can generate a startup signal through a gesture control or a display position on the decoding interface 235 (ie, the position of the image d1 displaying the two-dimensional barcode). The operation processing component 210 is caused to cause the arithmetic processing component 210 to start decoding the image d1 of the two-dimensional barcode according to the activation signal. Furthermore, the user can drive the decoding device 200 to decode by clicking on the image d1 of the two-dimensional barcode on the decoding interface 235 or by performing a gesture in the virtual space. The decoding device 200 can also start decoding the image d1 of the two-dimensional barcode through other means, which is not limited in this creation.

Next, the arithmetic processing unit 210 decodes the image d1 of the two-dimensional barcode to generate a ciphertext information. The ciphertext information is a horizontal image Im having one of the compressed one-dimensional barcodes 1D, as shown in FIG. 2B. The horizontal image Im is laterally captured at a position adjacent to one of the horizontal center lines Lc of the one-dimensional bar code 1D, and the horizontal image Im has a portion of each black bar Lb and a portion of each of the white bars Lw. The ciphertext information has been described in the embodiment of encoding the above two-dimensional barcode, and therefore will not be described herein. In the process of encoding the two-dimensional barcode (such as the embodiment of encoding the two-dimensional barcode), if the ciphertext information has an image start code and an image end code, the operation processing component 210 can be based on the image start code and the image. The end code decodes the image of the 2D barcode into a ciphertext information through a two-dimensional array data structure algorithm. The ciphertext information can also be calculated by other data structure algorithms. This creation does not limit this.

In other embodiments, if in the process of encoding the two-dimensional barcode (such as the embodiment of the encoding of the two-dimensional barcode described above), the plaintext information (ie, having one or a combination of text information and a digital information) is encoded to The two-dimensional barcode, the operation processing component 210 can decode the image d1 of the two-dimensional barcode to generate plaintext information and ciphertext information. The information about the plain text and the ciphertext are described in the embodiment of the encoding of the above two-dimensional barcode, and therefore will not be described herein.

Similarly, in the process of encoding the two-dimensional barcode, if the ciphertext information has an image start code and an image end code, the text information has a text start code and a text end code, and the digital information has a digital start code. And a digital end code, the operation processing component 210 can transmit the image of the two-dimensional barcode through a two-dimensional array data according to the image start code, the image end code, the text start code, the text end code, the digital start code, and the digital end code. The structure algorithm is decoded into ciphertext information and plaintext information.

Similarly, in the process of encoding a two-dimensional barcode (such as the above-described embodiment of encoding a two-dimensional barcode), if the ciphertext information is encrypted by the RSA algorithm, and the image of the two-dimensional barcode is superimposed with at least one recognition image (as shown in the figure) The recognition image d2 and d3) shown in FIG. 3B, the operation processing component 210 can remove the recognition image superimposed on the image d1 of the two-dimensional barcode before decoding the image d1 of the two-dimensional barcode (the recognition image d2 shown in FIG. 3B) With d3). And after the ciphertext information is generated, the arithmetic processing component 210 will decrypt the ciphertext information through the RSA algorithm. However, those skilled in the art should know to remove the identification image superimposed on the image d1 of the two-dimensional barcode and the implementation and operation of decrypting the ciphertext information through the RSA algorithm, and therefore will not be described herein. Of course, if the ciphertext information is encrypted by a specific encryption algorithm, the operation processing component 210 decrypts the ciphertext information in a decryption algorithm corresponding to one of the specific encryption algorithms, which is not limited in this creation.

After decoding the image d1 of the two-dimensional barcode to generate the ciphertext information, the operation processing component 210 decompresses the ciphertext information to generate the horizontal image Im of the uncompressed one-dimensional barcode 1D. In this embodiment, since the horizontal image Im is compressed by a run-length encoding (RLE) method in the process of encoding the two-dimensional barcode (such as the above-described embodiment of encoding the two-dimensional barcode), the horizontal image Im is compressed by a run-length encoding (RLE) method. Ciphertext information. Therefore, when the ciphertext information is decompressed, the operation processing component 210 decompresses the ciphertext information through a run-length decoding (RLD) method to generate a horizontal image Im of the uncompressed one-dimensional barcode 1D. . However, those skilled in the art should know the implementation and operation mode of the run length decoding mode, and therefore will not be described here. Of course, if the horizontal image Im is compressed by a specific encoding method to form ciphertext information, the arithmetic processing unit 210 decompresses the ciphertext information through a decoding method corresponding to one of the specific encoding modes, which is not limited in the present invention.

Next, the arithmetic processing unit 210 will longitudinally expand the uncompressed horizontal image Im by a code height to generate an image representing the one-dimensional barcode 1D. As shown in FIGS. 5A and 5B, after generating the horizontal image Im of the uncompressed one-dimensional barcode 1D, the arithmetic processing unit 210 will vertically expand the horizontal image Im such that the horizontal image Im is longitudinally expanded by one code height VH to become a one-dimensional representation. Barcode 1D image Im1. Since the horizontal image Im carries the thickness characteristic relationship between the plurality of black bars and the plurality of white bars, the image Im1 after the horizontally extending horizontal image Im also carries the thickness relationship between the plurality of black bars and the plurality of white bars, so that The image Im1 can analyze the image Im1 through a general barcode reader to obtain the information content of the one-dimensional barcode 1D.

As can be seen from the above, in the decoding process, the decoding device 200 reversely decodes the two-dimensional barcode according to the process of encoding the two-dimensional barcode to generate one or a combination of the image Im1 representing the one-dimensional barcode 1D and the text information and the digital information. Information. Accordingly, the user can initially know the information usage represented by the image Im1 from the text information or the digital information, and can analyze the image Im1 to obtain the information content of the one-dimensional barcode 1D.

The following will further introduce the invoice of a consumer after consumption, as shown in Figure 3B, its one-dimensional bar code feature, text information "August invoice" and digital information "12345678" are encoded in two dimensions superimposed with identification images d2 and d3. The bar code image d1 is stored in the store 70 with NFC sensing. At this time, when the consumer handheld decoding device 200 approaches the device 70, the decoding device 200 will receive the image d1 of the two-dimensional barcode with the invoice information transmitted by the device 70, and let the consumer click and decode for the consumer to see. A more detailed description of the information to the invoice itself, as shown in Figure 6A.

After the decoding device 200 decodes the image d1 of the two-dimensional barcode, as shown in FIG. 6B, the decoding interface 235 can display the content of the image Im1 representing the one-dimensional barcode 1D, the text information "August invoice" and the digital information "12345678". . After the invoice is awarded and the winning is determined, the consumer can carry the decoding device 200 of the image d1 of the two-dimensional barcode containing the invoice information to the awarding unit (such as the post office, the store, the convenience store) having the device 70 for the bonus redemption. Or return to households, or consumption, to save unnecessary paper waste. The decoding method for the two-dimensional barcode has been described in the above embodiments, and therefore will not be described herein. It should be noted that, in this embodiment, the device 70 may also be a device with other transmission functions, such as a smart phone, a tablet computer, a wearable device, and a wireless communication transmission with a telecommunication communication module or a network communication module. Modules such as POS machines, multimedia guides (KIOSK), or various electronic device connection combinations, this creation does not limit this.

In other embodiments, as shown in FIG. 7, the general device can use the encoding device 100 to transmit the image e1 of the two-dimensional barcode with the coupon information to the second transmission component 220 of the decoding device 200 of the client through the short message. .
