| QR-Code was invented in 1994 by a team led by Masahiro Harada of the Japanese company Denso Wave, based on the barcode originally used to mark automobile parts. It is a two-dimensional matrix barcode that can achieve multiple uses. QR-Code has the following advantages compared with one-dimensional barcodes: QR-Code can store more information because it uses a two-dimensional square matrix instead of one-dimensional lines. One-dimensional barcodes can usually only store dozens of characters, while QR-Code can Stores thousands of characters. QR-Code can represent more data types, such as numbers, letters, binary, Chinese characters, etc. One-dimensional barcodes can usually only represent numbers or letters. QR-Code can be scanned and recognized faster because it has four positioning marks and can be scanned from any angle. One-dimensional barcodes usually need to be scanned from a specific direction. QR-Code is more resistant to damage and interference because it has error correction capabilities that can recover partially lost or obscured data. One-dimensional barcodes generally do not have such capabilities. The difference between two-dimensional barcodes and one-dimensional barcodes mainly lies in the encoding method and information capacity. Two-dimensional barcodes use a two-dimensional square matrix, which can store more information and represent more data types. One-dimensional barcodes use one-dimensional lines, can only store a small amount of information, and can only represent numbers or letters. There are other differences between two-dimensional barcodes and one-dimensional barcodes, such as scanning speed, error correction capabilities, compatibility, etc. QR-Code is not the only two-dimensional barcode. According to the principle, two-dimensional barcodes can be divided into two categories: matrix and stacked. Common two-dimensional barcode types are: Data Matrix, MaxiCode, Aztec, QR -Code, PDF417, Vericode, Ultracode, Code 49, Code 16K, etc., they have different applications in different fields. The two-dimensional barcode developed on the basis of the one-dimensional barcode has advantages that the one-dimensional barcode cannot compare with. As a portable data file, although it is still in its infancy, it is in the ever-improving market. Driven by the economy and rapidly developing information technology, coupled with the unique characteristics of 2D barcodes, the demand for the new technology of 2D barcodes in various countries is increasing day by day. |
| Barcode Apps for Food Tracking: Apps that record the nutritional content, calories, protein and other information of the food you eat by scanning the barcode on the food label. These apps can help you record your eating habits, Manage your health goals, or understand where your food comes from. Transportation and logistics: Used for ordering and distribution codes, product warehousing management, logistics control systems, ticket sequence numbers in international aviation systems. Barcodes are used in ordering and distribution in the logistics and transportation industry. They can be used to string Line Shipping Container Codes (SSCCs) are encoded to identify and track containers and pallets in the supply chain. They can also encode other information such as best before dates and lot numbers. Internal supply chain: internal management of the enterprise, production process, logistics control system, ordering and distribution codes. Barcodes can store various information, such as item number, batch, quantity, weight, date, etc. This information can Used for tracking, sorting, inventory, quality control, etc., to improve the efficiency and accuracy of the company's internal supply chain management. Logistics tracking: Barcodes are widely used in logistics tracking. It can be used to identify goods, orders, prices, inventory and other information. By affixing barcodes on packaging or shipping boxes, it is possible to achieve warehouse entry and exit. Automatic identification and recording of distribution, inventory and other logistics information to improve the accuracy and efficiency of logistics management. Production line process: Barcodes can be used for factory production line process management to improve production efficiency and quality. Barcodes can identify product numbers, batches, specifications, quantities, dates and other information to facilitate traceability during the production process. Inspection, statistics and other operations. Barcodes can also be integrated with other systems, such as ERP, MES, WMS, etc., to achieve automatic collection and transmission of data. |
