However, for most consumers, almost all of them encounter purchases of expired products, deliberate illegal use of additives, false labels or counterfeiting in the stores. Counterfeiting and other issues. Generally speaking, some consumers will confirm the effective date on the packaging before purchasing the product, but because the location and method of marking the effective date are inconsistent, it is not easy to interpret, and it is even more difficult to read whether the content of the add-on conforms to the norm in the transaction, and When the problem occurs, consumers or vendors cannot immediately identify the affected product and its batch number.

In addition, in order to solve the product identification problem, most of the current GS1 global product coding standards are used to provide products with a product model identification mark. When consumers buy products, it is conducive to system identification. However, the current GS1 barcode format only encodes products according to the product model, but during the manufacturing process of the product, from the production end, logistics end, processing plant end, inspection end to the consumer end, the process is quite tedious and the information is huge. Conduct product coding and on-site inspection for the detailed information of products in each process. When there is a problem with the source of a raw material or does not meet the relevant specifications, the problematic product that has been circulated or sold on the market is difficult to effectively recycle There is no guarantee that it will not be sold to consumers.

The internal communication interface 41 is used for wired or wireless transmission connection with the transmission module 24 of the barcode processing device 20 and receives the custom code 90 transmitted by the barcode processing device 20. The data screening module 42 is used to select the code content to be verified from the custom code 90. The verification module 43 sets at least one preset condition for verifying whether the encoded content in the selected custom code 90 meets the preset condition. The external communication interface 44 is used to transmit the custom code 90 to a database 50.

As shown in FIG. 3, the database 50 may be a closed database 51 or an open database 52. The closed database 51 may be used internally by the enterprise. For example, the closed database 51 includes but is not limited to Supplier database, manufacturer database, inspector data, logistics provider database or warning database. The open database 52 is open to the public in accordance with the requirements of government regulations. For example, the open database 52 includes but is not limited to unqualified databases and qualified registration databases.

After the verification module 43 of the server 40 verifies whether the custom code 90 meets the preset condition, the server 40 transmits the condition verification result to the barcode processing device 20 through the internal communication interface 41, so that the barcode processing device 20 passes the transmission mode The group 24 receives the condition verification result reported by the server 40, and the processing program 222 of the analysis module 22 determines whether the condition verification result meets the regulations If the condition verification result does not meet the requirements, the processing program 222 will control the warning module 25 to issue a warning message. The warning message may be light, image, sound, vibration, or a combination thereof, depending on the actual application. For example, the present invention can also use the indicator light of the general barcode reading device 10 as the warning module 25, and the analysis module 22 of the barcode processing device 20 controls the positioning indicator light to prompt the operator by flashing. If the condition verification result meets the requirements, the processing program 222 displays the real-time status message according to the operation specified by the condition verification result.

Please refer to FIG. 4, which is a schematic flowchart of the barcode reading method of the present invention, and includes the following steps: Step 210: Obtain at least one barcode image of the product with a default barcode reading device, and then parse it with a barcode processing device The barcode image gets a product code and a custom code; Step 220: The barcode processing device confirms whether the product code is correct. If the product code is correct, the barcode processing device transmits the custom code to a server for verification and comparison; and steps 230: The server determines whether the custom code meets the preset conditions. If not, the server returns the verification result of the product condition to a barcode processing device for warning.

In step 210, the barcode reading device 10 scans and reads at least one barcode image 70 on the product to obtain a one-dimensional barcode image 71, a two-dimensional barcode image 72, or a one-dimensional barcode image 71 and a two-dimensional barcode at the same time The image 72, and the decoding module 21 of the barcode processing device 20 parses the one-dimensional barcode image 71 to obtain the general information of the product code 80. Common information includes a start code, a data code, and a check code. (check code), end code (end code), such as a The dimensional barcode image 71 can be EAN13, EAN8, UPC-A, UPC-E and other related barcodes, but not limited to this.

Similarly, the decoding module 21 of the barcode processing device 20 parses the two-dimensional barcode image 72 to obtain the custom code 90 of this product. The so-called custom code 90 refers to adding additional specific information when the two-dimensional barcode is generated. For example, supplier registration information, manufacturer registration information, inspector registration information, logistics supplier registration information, vendor registration information, origin, manufacturing date, effective date and other information, but not limited to this, the custom code 90 series will The resume information of the product itself is more fully recorded and presented.

In other words, when a product is being manufactured or manufactured, the manufacturing history of the product (such as supply, manufacturing, logistics, inspection, or sales) is registered in the server 40, and according to the type attribute of the product, from Select the required information from the product's resume information, that is, the custom code 90, and generate a two-dimensional barcode image or composite barcode image containing the custom code 90 through the label generation system. This two-dimensional barcode will be output and pasted on On this product.

In step 220, after the decoding module 21 parses to obtain the product code 80 or the custom code 90, the processing program 222 of the analysis module 22 first checks to verify whether the product code 80 is correct. 221 transmits the custom code 90 to the encryption module 23 for encryption, and transmits the custom code 90 to the server 40 through the transmission module 24 for comparison.

In step 230, after the internal communication interface 41 of the server 40 receives the custom code 90, the data filtering module 42 of the server 40 can select the code content to be verified and compared among the custom codes 90, and then The verification module 43 verifies whether the encoded content matches the preset For example, when there is a problem with a raw material supply source or the manufacturer’s production does not comply with the relevant regulations, the verification module 43 will immediately report the result of the condition verification to the analysis module 22 of the barcode processing device 20 through the internal communication interface 41. 222 controls the warning module 25 to display a warning message, and the processing program 222 notifies the checkout device 30 to stop consumption checkout. If the verification module 43 matches the custom code 90 and meets the preset condition, the processing program 22 will transfer the product code 80 to the checkout device 30 for checkout consumption, or the operation specified by the processing program 222 according to the condition verification result Display real-time status messages.

In the present invention, the best way is to first confirm whether the product code 80 of the product to be consumed is correct by the barcode processing device 20. If the product code 80 of the product itself is confirmed to be correct, the custom code 90 is transmitted to the server 40 Perform verification to confirm whether the custom code 90 of the product meets the preset conditions. If the server 40 verifies that the custom code 90 meets the preset condition, the checkout device 30 will be activated to perform the consumption checkout.

In the present invention, another application method is that after reading the two-dimensional barcode image 72 of the product with the barcode reading device 10, the parsed custom code 90 can be uploaded to multiple pieces through the server 40 by the barcode processing device 20 The database 50 is registered and stored. In other words, it uses network cloud devices to register the custom codes 90 read by various products to the server 40 for verification, and extensively collects and summarizes these databases 50 to establish a standard supplier. A unified platform for registration information, manufacturer registration information, inspector registration information, logistics dealer registration information, or seller registration information.

The present invention cites an example of an over-the-counter retail food as an illustration, but does not limit the patent application scope of the present invention. For example, when a super clerk reads with the barcode reading device 10 After the one-dimensional barcode image 71 and/or the two-dimensional barcode image 72 of a food, the product code 80 of the food can be obtained by the bar code processing device 20. The product code 80 includes relevant information such as food items, selling prices, etc. The barcode processing device 20 confirms that the product code 80 of the food is correct. At the same time, the barcode processing device 20 also obtains the custom code 90 of the food, and uploads the custom code 90 to the server 40 via the transmission module 24 for verification. If an added raw material of the food violates the food safety regulations or the expiration date has expired, the server 40 can return real-time status information to the barcode processing device 20, and control the warning module 25 to display the warning message. At this time, the super clerk can immediately know that the food the consumer wants to buy has problems and cannot be sold.

In this way, when various types of foods are circulated in large quantities on the market, when there are problems in the supply of raw materials, manufacturing processes or logistics distribution processes, or when unqualified foods are sold, the instant The barcode reading method and system for status reporting can immediately know whether the food complies with the current manufacturing specifications or relevant regulations when reading the barcode image of the food. If a warning message appears, the food can also be processed immediately. Sale or additional recycling. In this way, problems such as illegal additives or false labels are eliminated to ensure the safety of food.

The present invention cites another embodiment as an illustration, but does not limit the scope of patent application of the present invention. For example, after the original manufacturer manufactures the manufactured product, the custom code 90 required for the relevant production history retrieval can be made into a two-dimensional barcode, and then the two-dimensional barcode can be set on the product. When the consumer purchases this product, he can read the two-dimensional barcode image 72 of the product and connect the custom code 90 of the two-dimensional barcode image 72 to the server 40 for verification. If there is no such custom code 90, the product can be judged as counterfeit to avoid consumers buying counterfeit products. In the present invention, after reading at least one barcode image of a product and obtaining a product code and a custom code, after the bar code processing device confirms the product code information, multiple databases of the server compare whether the custom code meets the preset Condition, and then confirm the current real-time status of the product, and the server sends the verification result of the product's condition back to the barcode processing device for warning, which can effectively eliminate the problematic products on the market and register the custom code to the real-time The multiple databases of the server are extensively collected and summarized to establish a standard unified platform. The present invention can also use the uniqueness or batch nature of the custom code to apply to the simultaneous data collection of the product code and the custom code and upload it to the closed database 51 or the open database 52 for management to facilitate the establishment of product traceability Management and other applications.
