1. Comparison of barcode inventory and RFID tag inventory
Regarding warehousing inventory, this is a commonplace question, but almost all companies need to carry out warehouse inventory. The difference is nothing more than the size and quantity of the warehouse.
At present, half of the warehousing inventory is managed by barcodes. The commonly used symbologies in the world include EAN barcodes, UPC barcodes, 25 barcodes, cross 25 barcodes, Coudba barcodes, 39 barcodes and 128 barcodes, etc. The most commonly used ones on commodities It is the EAN product barcode. This kind of commodity barcode is also being promoted in our country.
Although the application of barcodes has made warehouse inventory very convenient, with the introduction of electronic labels and the daily use of barcodes, some limitations of active barcodes themselves will cause some problems in the inventory process, resulting in omissions in inventory. The introduction of electronic tags can just make up for these problems. We can compare the characteristics of barcodes and RFID tags through the following table.

|
Tag data can be read and written repeatedly
|
|
Reading convenience and safety
|
The label is visible and clear when reading, and can be read by any compatible scanner, with low security
|
Can be read directly by scanner, can be encrypted, high security
|
The data can be read when placed on the surface of the item or hidden in the package, which is relatively safer than the barcode
|
|
Data correctness
|
Need to rely on manual reading, there is a possibility that someone may make mistakes in the operation

|
RFID can automatically transmit data for easy tracking and storage of goods
|
|
Stain resistance and durability
|
Destroyed barcodes will not be readable
|
Defaced not more than 50% can still read and take out the complete information
|
The surface is contaminated / can still be read normally in harsh environments
|
|
Reading and writing direction

It can be seen from the above table that RFID tags are advantageous from the comparison of more than 10 aspects such as the number of readings and speed, reading distance, anti-fouling ability, and durability. Therefore, Tangan Wulian believes that upgrading the traditional bar code inventory to an RFID storage inventory system has advantages and operability, which can bring convenience to the daily inventory and warehousing work of enterprises.
2. The characteristics of RFID storage inventory and warehousing system
1. The surface of the RFID tag is contaminated, which can also ensure the normal reading of the data and can be reused, saving the investment cost of the enterprise
2. For items in and out of the warehouse, there is no need for human intervention, and multiple items can be identified at a long distance at the same time to improve the accuracy and efficiency of in and out of the warehouse.
3. RFID handheld reader has the characteristics of fast recognition speed, large quantity, long distance, etc., which can realize fast inventory of goods in stock
4. The visualized information platform provides users with timely access to inventory status, provides convenience for the rational allocation of resources, and realizes tracking of inventory products
3. RFID warehousing inventory system functions:
The entire system is composed of two terminals: a web page and a handheld terminal, and the warehouse inventory staff can independently choose according to daily operation requirements. The handheld terminal uses mobile APP as the daily inventory system, which is more convenient in operability.
Web-side warehouse management system functions:
1. Basic data: supplier management, department management, product category management, and product management
2. Warehousing management: purchase warehousing, warehousing statistics
3. Outbound management: departmental use, outbound statistics
4. Inventory: inventory query, inventory change statistics, inventory alert
5. System management: administrator settings
Handheld terminal warehouse management functions:
1. Inventory counting: counting statistics, which can be exported to Excel
2. Warehousing management: scan the warehousing goods for warehousing processing and record the database
3. Outbound management: scan the outbound goods to make warehouse processing and record the database
4. Special treatment: scrap, requisition, transfer, etc. of goods
Warehouse management is a very important part of enterprise management, especially logistics management. The quality of management will directly reflect the level of standardized management quality and also reflect the comprehensive ability of the enterprise to participate in market competition.
The higher the efficiency of the material turnover in the warehouse, the faster the market turnover rate of the company’s products, the better the business effect of the company.
The more accurate and detailed the quantity of materials in the warehouse, it directly guides the business decision-making of the enterprise and also provides financial data for the enterprise. In order to make the management of the warehouse meticulous, the materials intact, and the data accurate, to give play to the effect of the warehouse in logistics and the role in management, it is necessary to use a convenient and easy-to-use warehouse inventory and storage system.
