With the same amount of information, the shape of the PDF417 barcode can be adjusted according to the carrier area and art design. The encoding range is wide. PDF417 barcode can encode all digital information such as photos, fingerprints, palm prints, signatures, voices, and texts.
1. Overview:
Whether in the ERP system or the MRP / â…¡ system, if the basic data collection and transmission are not true, the data obtained by the decision system becomes meaningless. Analysis of the reasons for the failure of some domestic enterprises to implement the ERP system will also find that the failed data collection has led to the failure of the entire system.
In terms of data collection and data transfer, the two-dimensional barcode has natural advantages. First, the storage capacity of the two-dimensional barcode PDF417 is up to thousands of bytes, so it can effectively store the information of goods; The error correction algorithm can still restore the complete original information in the case of partial damage. Therefore, the use of PDF417 to store and transfer the information of commodities is safe, reliable, fast and convenient.
The use of two-dimensional barcodes as the carrier of information transmission in the supply chain can not only effectively avoid possible errors in manual input, but also greatly improve the efficiency of warehousing, warehousing, order making, inspection, and inventory, as well as delivery identification and warranty. Recognition and other functions can also achieve offline management in the case of inconvenience online.
The use of two-dimensional barcodes will advance the management of commodities to Economic Cell Management, which can manage and track products from a deeper level.
2. Barcode features: (PDF417 two-dimensional barcode)
The PDF417 barcode is a high-density, high-information, portable data file. It is an ideal means to realize the automatic storage, carrying, and automatic reading of large-capacity, high-reliability information such as certificates and cards. The PDF417 barcode has the following characteristics:
Large information capacity
Each square inch can hold 250 to 1100 characters according to different bar space ratios. On the effective area of ​​the international standard card (equivalent to 2/3 of the area of ​​the credit card, about 76mm * 25mm), the PDF417 barcode can accommodate 1848 alphabetic characters or 2729 numeric characters, and about 500 Chinese characters. This two-dimensional barcode has several dozen times higher information capacity than ordinary barcodes.
High decoding reliability
The decoding error rate of ordinary barcodes is about two parts per million, while the error rate of PDF417 barcodes does not exceed one ten millionth, and the decoding reliability is extremely high.
Strong ability to correct errors
PDF417 barcode adopts the world's most advanced mathematical error correction theory. In the case of Level 8 security, if the damaged area does not exceed 50%, the information lost by the barcode due to contamination, damage, etc., can be decoded as usual.
Easy to make and low cost
Using existing dot matrix, laser, inkjet, thermal / thermal transfer, card machine and other printing technologies, PDF417 2D barcodes can be printed on paper, cards, PVC, and even metal surfaces. The increased cost is only the cost of ink, so people call PDF417 "zero cost" technology.
Variable barcode symbol shape
With the same amount of information, the shape of the PDF417 barcode can be adjusted according to the carrier area and art design.
Wide coding range
The PDF417 barcode can encode all digital information such as photos, fingerprints, palm prints, signatures, sounds, and text.
Good confidentiality and anti-counterfeiting performance
PDF417 barcode has multiple anti-counterfeiting features, it can use password anti-counterfeiting, software encryption and use the contained information such as fingerprints, photos, etc. for anti-counterfeiting, so it has extremely strong security anti-counterfeiting performance.
3. Barcode application:
Product tracking on the production line (as shown below)
In daily production, track the production process of products.
²Firstly, the business center issues the production task order, and the task order flows with the corresponding products.
² Then at the beginning of each production link, use the production line terminal to scan the barcode on the task list to change the product status in the database. ² When the final product is packaged offline, print and paste the customer information barcode of the product.
Note 1: The customer information barcode label can be made of PVC material, which has high strength, is not afraid of water, is resistant to high temperatures, and has good anti-aging properties.
Product label management
The product label is printed and pasted by the manufacturer on the obvious position of the product packaging when the product leaves the production line. Product labeling will become an important symbol for tracking product flow.
If the product manufacturer does not provide a barcode label or the label is damaged, you can use the product label management module provided by the system to regenerate the required label.
Product storage management
When entering the warehouse, read the two-dimensional barcode label on the product, and enter the storage information of the product at the same time, store the characteristic information and the storage information of the product together in the database, and check the storage to see if it is a duplicate entry.
Transmitting information through two-dimensional barcodes effectively avoids errors in manual entry, realizes lossless transmission and rapid entry of data, and advances the management of commodities to a deeper level-individual management.
Product Outbound Management
According to the delivery note or distribution note generated by the business center, select the corresponding product out of the warehouse. For the convenience of stocking and stocking, you can make a combined query based on the characteristics of the product, you can print the query results or generate data files that can be used for mobile terminals.
When the product is out of stock, it is necessary to scan the two-dimensional barcode on the product to confirm the information of the outgoing product and change its inventory status.
Warehouse internal management
In inventory management, on the one hand, two-dimensional barcodes can be used for inventory counting, and the inventory of commodity information can be collected through a handheld wireless terminal. Then, the collected information is processed by the computer to form an inventory report. On the other hand, two-dimensional barcodes can be used for stocking.
Cargo delivery
Two-dimensional barcodes are of great significance in distribution management. Before distribution, download the distribution product information and customer and order information to the mobile terminal. After reaching the delivery customer, open the mobile terminal, first call the customer's corresponding order, and then select the goods according to the order and verify their barcode label. After confirming the delivery of a customer's goods, the mobile terminal will automatically verify the delivery situation and make corresponding prompts.
Warranty maintenance
The maintenance personnel use the reader to read the customer information barcode information label to confirm the product information. After the maintenance is completed, enter the maintenance situation and related information.
