Bar code preparation method is as follows:
1, select the bar code type: according to the type of items need to be identified, select the appropriate bar code standard, such as EAN, UPC, Code39, etc..
2. Prepare data: Prepare the data to be encoded, generally including numbers, letters and special characters.
3, encoding: use the barcode encoder to convert the data into a barcode pattern. This process involves some algorithms and rules, for example, for numeric characters, you need to use the corresponding code system for encoding.
4, drawing bar code: according to the results of the encoding, the use of bar code drawing software to draw the data into a bar code. This process needs to pay attention to the size of the bar code, color, contrast and other parameters to ensure that the bar code can be correctly identified.
5, verification: in the completion of the bar code drawing, the need for verification to ensure data integrity and correctness. The calibration method generally uses a certain algorithm to calculate the bar code, resulting in a check digit, and the check digit and the bar code to compare the check digit, if the same is the bar code is correct, otherwise the bar code is wrong.
Bar code application:
1, commodity circulation management
Bar code plays an important role in commodity circulation management. By labeling the goods with barcode labels, you can realize the effective tracking and management of goods. In the process of purchase, sale and return, the use of barcode scanners can quickly and accurately read commodity information and improve management efficiency. In addition, by combining the bar code with the information system, it can also realize the functions of inventory management and sales analysis, providing powerful support for enterprise decision-making.
2, health care
In the field of health care, bar code also has a wide range of applications. For example, in drug management, by labeling drugs with barcode labels, effective tracking and management of drugs can be realized to ensure the quality and safety of drugs. In addition, barcodes also play an important role in medical equipment and patient information. Through the use of bar codes, information such as patient information and equipment status can be read quickly and accurately, improving the efficiency and quality of medical services.
3, Logistics and Supply Chain Management
Barcodes are also widely used in logistics and supply chain management. In logistics, through the use of barcode technology, it can realize the fast and accurate identification and tracking of goods and improve the efficiency of logistics. In supply chain management, through the combination of bar code and information system, it can realize the whole tracking and management from raw material procurement to final product delivery, and ensure the reliability and efficiency of supply chain.
Through the use of barcode technology, it can also realize the automated sorting of goods and rapid distribution and other functions to improve the efficiency and quality of logistics and supply chain management.
