With the same amount of information, the shape of the PDF417 barcode can be self-adjusted according to the area of the carrier and the design of the artwork. With a wide range of codes, PDF417 barcodes can encode digitally identifiable information such as photos, fingerprints, palm prints, signatures, sounds, and text.
1. Summary:
Whether in the ERP system or in the MRP/II system, if the underlying data is collected and transmitted inaccurately, the data obtained by the decision system becomes meaningless. Analysis of the reasons for the failure of some domestic enterprises to implement ERP system, it will also find that the failure of data collection leads to the failure of the entire system.
In terms of data acquisition and data transmission, 2D barcodes have natural advantages. First, the storage capacity of 2D barcode PDF417 is up to thousands of bytes, so it can effectively store the information of goods. Secondly, because PDF417 adopts advanced The error correction algorithm can still restore the complete original information in the case of partial damage. Therefore, the use of PDF417 to store the information and materials of the goods is safe, reliable, fast and convenient.
In the supply chain, the use of two-dimensional bar code as the carrier of information transmission can not only avoid the mistakes that may be caused by manual input, but also greatly improve the efficiency of warehousing, delivery, order making, inspection and inventory, and also have distribution identification and warranty. Recognition and other functions can also be managed offline without the need for online connection.
The use of 2D barcodes to advance the management of commodities to Economic Cell Management allows for the management and tracking of products from a deeper level.
2. bar code features: (PDF417 two-dimensional bar code)
PDF417 barcode is a high-density, high-information portable data file. It is an ideal means for automatic storage, carrying and automatic reading of large-capacity and high-reliability information such as documents and cards. The PDF417 barcode has the following characteristics:
Large information capacity
It can hold 250 to 1100 characters per square inch depending on the width of the strip. In the effective area of the international standard card (equivalent to 2/3 of the credit card area, about 76mm*25mm), the PDF417 barcode can hold 1848 alphabetic characters or 2729 numeric characters, about 500 Chinese characters. This two-dimensional barcode is several times more powerful than ordinary barcode information.
High decoding reliability
The decoding error rate of ordinary barcodes is about 2 parts per million, while the error rate of PDF417 barcodes is less than one ten-thousandth of a million, and the decoding reliability is extremely high.
Strong ability to correct errors
The PDF417 barcode uses the world's most advanced mathematical error correction theory. In the case of eight-level safety, if the damaged area does not exceed 50%, the information lost due to contamination, damage, etc., can be deciphered as usual.
Easy to make and low cost
PDF417 2D barcodes can be printed on paper, cards, PVC, and even metal surfaces using existing dot matrix, laser, inkjet, thermal/thermal transfer, and card-making machines. The added cost is only the cost of ink, so PDF417 is also called "zero cost" technology.
The shape of the bar code symbol is variable
With the same amount of information, the shape of the PDF417 barcode can be self-adjusted according to the area of the carrier and the design of the artwork.
Wide range of codes
The PDF417 barcode encodes digitally identifiable information such as photos, fingerprints, palm prints, signatures, sounds, and text.
Good confidentiality and anti-counterfeiting performance
The PDF417 barcode has multiple anti-counterfeiting features. It can use password anti-counterfeiting, software encryption and use of information such as fingerprints, photos, etc. for anti-counterfeiting, so it has strong security and anti-counterfeiting performance.
3. Barcode application:
Product tracking on the production line (as shown below)
In the daily production, the production process of the product is tracked.
First, the business center releases the production task list, and the task list follows the corresponding products for flow.
Then at the beginning of each production step, use the production line terminal to scan the barcode on the task list to change the product status in the database.
When the final product is offline, print and paste the customer information barcode of the product.
Note 1: The customer information barcode label can be made of PVC material. The PVC material has high strength, is not afraid of water, and is resistant to higher temperatures, and has good anti-aging properties.
Product label management
The product label is printed and pasted by the manufacturer at a prominent location on the product packaging as it moves down the production line. Product labeling will be an important indicator of tracking product flow.
If the product manufacturer does not provide a bar code label or the label is damaged, the product label management module provided by the system can be used to regenerate the required label.
Product warehousing management
When the warehousing, the two-dimensional bar code label on the product is read, and the storage information of the product is entered at the same time, and the characteristic information and the storage information of the product are stored in the database together, and the storage is checked to see if it is repeatedly entered.
The information is transmitted through the two-dimensional barcode, which effectively avoids the mistake of manual entry, realizes the lossless transmission and fast entry of the data, and promotes the management of the commodity to a deeper level - individual management.
Product outbound management
According to the bill of lading or delivery order generated by the business center, select the corresponding product out of the warehouse. It is convenient for stocking out of the warehouse, and can be combined and inquired according to the characteristics of the product, and the query result can be printed or a data file usable for the mobile terminal can be generated.
When the product is shipped out, the 2D barcode on the product is scanned, the information of the outbound product is confirmed, and the inventory status is changed.
Warehouse internal management
In the inventory management, on the one hand, the 2D barcode can be used for inventory counting, and the inventory information is collected through the handheld wireless terminal. The collected information is then centrally processed by a computer to form an inventory report. On the other hand, 2D barcodes can be used for outbound stocking.
Delivery of goods
The two-dimensional bar code has an important significance in the distribution management. Before the delivery, the delivery product data and the customer and its order data are downloaded to the mobile terminal. After arriving at the delivery customer, open the mobile terminal, first call out the corresponding order of the customer, then select the goods according to the order situation and verify the barcode label. After confirming the delivery of a customer's goods, the mobile terminal will automatically verify the delivery and make corresponding prompts.
Warranty maintenance
The maintenance personnel use the reader to read the customer information barcode information label and confirm the product information. After the repair is completed, enter the maintenance situation and related information.
