How Do Barcode Inventory Systems Work? The application of barcodes in warehousing:
Barcode warehouse management is a traditional field where bar code technology is widely used and mature. It is not only suitable for commercial commodity inventory management, but also applicable to factory product and raw material inventory management. Only the realization of electronic management of warehouse management (inventory) can make full use of product and raw material information resources. Warehouse management is dynamic. Through the establishment of the warehouse management (inventory) electronic system, managers can keep abreast of the current quantity and dynamic changes of each product or raw material on the shelves and warehouses, and quantitatively analyze various Information on product or raw material inventory, sales, production, etc. Through it, managers can make timely decisions on the quantity of purchases and adjust production to maintain optimal inventory, improve inventory structure, accelerate capital turnover, and achieve full control and management of products and raw materials.

(1) The characteristics of implementing barcode warehouse management (inventory) electronicization:
1, real-time data
Economical and easy-to-implement inventory management maintains the original logistics method and realizes the automation of information flow, that is, data collection automation, that is, the data acquisition system uses barcode automatic identification technology as a data input means to carry out each product or raw material operation (such as At the same time of arrival, inventory, inventory, the system automatically processes the relevant data, and prepares the data for the next operation (such as financial management, outbound), without stopping the operation.

2, "zero" error
Since the system almost eliminates the manual keyboard input of data in the logistics process, the possibility of data input errors in the inventory management process is greatly reduced.

3, provincial manpower, high efficiency
The real-time data and scientific decision-making of high-speed information flow enable low cost, low inventory, high capital turnover and high efficiency in order to ensure that the huge spare stock of supply can be greatly reduced or become unnecessary.
The three-dimensional warehouse is an important part of modern industrial production. Using barcode technology, it can complete the guidance, positioning and personality operation of warehouse goods, improve the recognition speed, reduce human error, and improve the warehouse management level.

(2) Application of barcode in warehouse management system
A management information system that collects and tracks the logistics information of enterprises by using barcode technology. Through the logistics tracking for the manufacturing industry, the company meets the information management needs of warehousing and transportation. The application of barcode coding and recognition technology solves the "bottleneck" problem of entering and collecting data in warehouse information management, and provides powerful technical support for the application of warehouse information management system.

1. Cargo inventory management
The warehouse management system classifies the goods according to the product name, model, specification, origin, brand, packaging, etc., and assigns a unique code, which is the “item number”. The item number manages the single item collection of the goods inventory and the management item number, and is applied to various operations of the warehouse.
2, warehouse location management
The warehouse is divided into several warehouses; each warehouse is divided into several warehouses. The warehouse is an independent and closed inventory space in the warehouse. The space in the warehouse is carefully defined as the location, and the subdivision can define the inventory space more clearly. The warehouse management system records the warehouse goods inventory according to the warehouse location. When the product is put into storage, the warehouse barcode number and the product barcode number are in one-to-one correspondence. When the warehouse is out of stock, the first-in-first-out or batch can be realized according to the inventory time of the warehouse goods. Secondary management information.
3, single item management
The product identification barcode is used to record the tracking management of the status products that the single product passes through.
4, warehouse business management
Including: out of the library, warehousing, library, monthly library, transfer library, different businesses in their own way, complete the import, sales, storage management of the warehouse.
5, more accurate completion of warehouse access
The warehouse uses the barcode to collect the single piece of information of the goods, processes the collected data, and establishes the inbound, outbound, transfer, and library data of the warehouse. In this way, the warehouse operation is completed more accurately. It can provide the location information of the warehouse goods out of the warehouse according to the single item inventory, so that the warehouse goods inventory is more accurate.
(3) Application of barcode in warehousing operations
Bar code application appears in almost all parts of the entire warehouse distribution operation process. Its application is beneficial to realize inventory management automation, reasonable control of inventory quantity, and automatic loading and unloading management of warehouse purchase, delivery and transportation. As an important means of data and information input, bar code has the characteristics of accurate input, fast speed and large amount of information. Below we briefly explain the application of barcodes in warehousing and distribution management.
1. Ordering: Whether the company orders from the supplier or the seller orders the enterprise, the order can be made according to the order book or shelf label. Regardless of the ordering method, the bar code scanning device can be used to input the barcode on the order book or on the shelf. This barcode contains information such as the product name, brand, origin, and specifications. Then, through the host, the network is used to notify the supplier or the distribution center of the order quantity and quantity. This ordering method is several times more efficient than traditional manual ordering.
2. Receipt: When the distribution center receives the goods sent from the supplier, the receiving staff will put a barcode on the product packaging box as the record of the corresponding shelves in the warehouse corresponding to the goods. At the same time, the barcode on the outer packaging of the product is scanned, the information is transmitted to the background management system, and the barcode of the package is in one-to-one correspondence with the barcode of the product.
3. Storage: The barcode is used for storage management. After the goods arrive, the basic information of the goods is input into the computer through the barcode input device, and the computer system is told which products to enter the warehouse. The computer system determines the storage location of the commodity according to the predetermined storage principle and the quantity of the commodity inventory. Then, a barcode label is issued according to the quantity of the product, and the barcode label contains information on the storage location of the product. Then label the container and place it on the conveyor. After the conveyor identifies the barcode on the container, place the container in the designated location area.
4, arranging goods: When placing goods manually, the porter should place the received goods on the shelves of the warehouse. Before carrying the goods, first scan the barcode on the box, the computer will prompt the workers to put the goods in advance. The assigned position, after the porter transports the goods to the designated location, scans the location barcode to confirm that the location is correct. In this way, the barcode plays a very important role in the whole process from the storage of the goods to the transportation to the storage of the goods. When the goods are put into the warehouse in trays, the arrival list is entered into the computer, and the barcode label issued according to the number of trays is obtained. Attach the barcode to the side of the pallet facing the forklift. A laser scanner is mounted on the front of the truck. The truck lifts the tray and places it in the position indicated by the computer. A sensor and emission display device, an infrared illuminating device, and a luminous graphic card indicating the cargo area are mounted on each of the pallet positions. After the forklift driver has placed the pallet, the information on the completion of the work is transmitted to the host computer through the terminal device mounted on the forklift. In this way, the goods' goods address is stored in the computer.
5, replenishment: find the inventory of goods, determine whether you need to purchase or whether the goods take up too much inventory, also need to use barcode to achieve management. In addition, since the commodity barcode and the shelf are one-to-one correspondence, the purpose of replenishment can also be achieved by checking the shelf. Barcodes not only play a role in the business processing of the distribution center, but also the data collection and management of the distribution center are inseparable from the barcode. Through the management of barcodes by computers, the collection of commodity operations and inventory data can timely understand the stock of goods on the shelves, so as to carry out reasonable inventory control, and reduce the inventory of goods to the lowest point; Reduce the loss of sales due to out-of-stock replenishment due to out of stock.
Due to the application of bar code and computer technology, the information transmission speed and the accuracy of the data are greatly improved, so that real-time logistics tracking can be realized, and the operation status of the entire distribution center and the inventory quantity of the goods are also reflected to the management and the time through the computer. Decision layer. In this way, it is possible to effectively control the inventory and shorten the circulation period of the goods. On the other hand, the use of bar code scanning instead of the original manual operation avoids human error, improves the accuracy of the data, and reduces the loss caused by mismanagement of the distribution center.
