With the development of the Internet of Things industry, RFID technology is gradually popularized and applied in our daily lives, bringing convenience and speed to people’s lives. The essence of RFID (Radio Frequency Identification) is to use radio frequency technology (RF) to realize the identity and information identification of items.
In the retail industry, the entire supply chain is interlinked from procurement, storage, packaging, loading and unloading, transportation, distribution, sales to service. Enterprises must accurately grasp the flow and changes of the entire business flow, logistics, information flow and capital flow in real time, while RFID effectively provides the retail industry with input/output of business operation data, control and tracking of business processes, and reduction Error rate etc. Therefore, RFID technology is very attractive to the retail industry that focuses on logistics and inventory management, and retail giants have also poured great enthusiasm for it.
This article will count the four application scenarios (cases) of RFID in the retail industry.
Application scenario 1: RFID-based supply chain management of supermarket stores
In recent years, the rapid development of RFID technology has brought leapfrog development opportunities for the supply chain management of the retail industry. With international retail giants such as Wal-Mart, Marks & Spencer, Metro, Albertson, Target and other international retail giants successively releasing the mandatory use of RFID supply chain management technology, the competition between the finished product supply chain has become the key to the success or failure of future competition in the retail industry.
Application Scenario 2: RFID-based inventory management of footwear retail enterprises
With the increasing penetration rate of RFID electronic tags in the retail industry, clothing has gradually begun to introduce RFID technology to the entire management system. It is expected that the penetration rate will increase rapidly in the next few years. According to statistics, by the end of 2016, the global chain retail industry, which is dominated by clothing, demanded more than 5 billion RFID tags. Such as foreign Decathlon, ZARA, Uniqlo, domestic Hailan House, La Chapelle, UR, etc. have all implemented RFID projects.
There are two main reasons for the high application of RFID electronic tags in the clothing industry: First, the tags in this scenario are consumables. Once the electronic tags are transferred to the final link, that is, consumers, the mission of the electronic tags will be completed; And another reason is that thanks to its lower and lower manufacturing costs, the average cost of a single electronic tag in this application scenario in China is less than 1 yuan, which is generally about the price of a piece of clothing. It’s less than 1%.
Application scenario 3: RFID application in unmanned convenience stores
There are many unmanned convenience stores, but they are basically inseparable from RFID technology. RFID tags are affixed to each item for checkout and collection. In addition, it is also equipped with a monitoring system, remote customer service and other functions.
Application Scenario 4: Application of RFID in Supply Chain Logistics
By using RFID technology, it is possible to improve the transparency of supply chain logistics management and inventory turnover, effectively reduce stock-out losses, and improve logistics efficiency within the enterprise.
One fast: fast logistics efficiency, fast delivery of goods, improve the efficiency of logistics operations;
Two standards: accurate data, accurate collection of goods circulation data in all aspects of logistics management.
According to the current status of warehousing management and the feasibility study of RFID technology in logistics management, embedding advanced RFID data collection methods in the WMS system can realize the management of RFID tag locations and pallets. In this way, it can not only realize the informationization and modernization of enterprise logistics management, but also improve the enterprise logistics management level and management efficiency, and reduce enterprise management costs.
From the perspective of the future development of Chinese and foreign logistics, network information construction is the future development trend of warehousing logistics. New technologies represented by radio frequency identification (RFID) are profoundly affecting warehouse management and warehouse management systems, and even gestating a “logistics revolution.”
Summary: RFID advantages and disadvantages
A study by Technavio Research shows that by 2019, the global retail RFID application market is expected to reach 3.91 billion U.S. dollars, and the compound annual growth rate of the global RFID market for such applications will reach 40% during the forecast period. Conceptually, RFID is similar to barcode technology. Barcode technology is to attach the barcode information to the article, and scan the barcode on the article through a scanner to obtain the information of the article. The RFID technology attaches the RFID tag to the item, and reads the information in the tag into the RFID reader through the radio frequency signal, thereby obtaining the unique information of the item.Compared with traditional barcodes, the advantages of FRID technology are as follows:
1. Quick scan
The RFID reader can identify and read multiple RFID tags at the same time. In contrast, only one barcode can be scanned at a time.
2. Penetrating and unbarred reading
When covered, RFID can penetrate non-metal or non-transparent materials such as paper, wood, and plastic, and can perform penetrating communication. The reason why “unmanned retail stores” can achieve unmanned cashiers is mainly due to the use of this feature of RFID technology.
3. Large data memory capacity
The capacity of a one-dimensional bar code is about 30 characters, the maximum capacity of a two-dimensional bar code can store 2 to 3000 characters, and the maximum capacity of RFID is several trillion characters. With the development of memory carriers, the data capacity is also expanding.
4. Small size and diversified shapes
RFID is not limited by size and shape in reading, and does not need to match the fixed size and printing quality of paper for reading accuracy. Unlike barcodes, they are prone to deformation and damage, which can lead to unrecognizable problems.
But in fact, although the current low frequency band and high frequency band have been widely used in China, such as campus cards, ID cards, mobile phone NFC modules, etc.; but in the consumer field, barcodes can basically meet the description of individual items and are being promoted. There is already a mature supporting system, and RFID tags cannot replace bar codes. Therefore, it is not an easy task to completely replace barcodes with RFID tags, and it faces at least the following challenges in terms of popularization:
1. Cost
Although the cost of RFID tags, readers and software has been declining, the cost of RFID deployment is still unaffordable for many companies that want to track product inventory.
2. Technical standards are difficult to unify
For RFID technical standards, it is currently difficult to achieve uniformity in the world, making product development and application positioning chaotic.
3. The accuracy of reading needs to be improved
Data integrity and correctness are important factors that determine the performance of RFID systems. Multi-target recognition is not only the biggest advantage of RFID, but also a technical difficulty that needs to be solved urgently.
