Help enterprises realize digital transformation
With the advent of a new retail era of online consumption and offline experience, the trend of unmanned stores has impacted the traditional retail and e-commerce platforms, promoting the consumption mode to further move towards the future of the combination of virtual and real. As one of the key technologies of unmanned store, RFID technology has become a solution that can compete with computer vision.
Radio frequency identification (RFID) is a kind of wireless communication technology developed since the Second World War. It identifies through wireless signals and has the function of reading and writing data. With the continuous optimization and improvement driven by the application of the Internet of things, today's technology has been quite mature and extended to different industries such as shoes and clothing, supermarkets, hotels, logistics, finance, access control and anti-theft, medical care, such as world-famous clothing brands Zara and UNIQLO, as well as mass merchandiser supermarkets Wal Mart and Carrefour, RFID tags are imported into their products and warehouse management.
Different from the light sensing principle of bar code and QR code, the core technology of RFID is to bury the chip and antenna in the light, thin and short label interlayer, which can not only provide one to many reading, reuse, high storage capacity, and can be read within 4 meters, but also does not need power drive. As long as you scan with a reader, you can easily collect goods, logistics, storage Revenue and other information can not only achieve the standardization of global warehouse management and logistics, but also accumulate big data of consumption patterns at the back end, which can be used as the analysis of future marketing strategies.
At present, the development of RFID technology is quite mature, and the application scenarios have been widely integrated into people's daily life. For example, traffic stored value cards such as suica in Japan and octopus in Hong Kong bury RFID tags in the cards. As long as there is a corresponding reader, it can provide people with the functions of stored value, payment, public transportation and card swiping customs clearance.
In today's most popular topic of unmanned store, RFID technology can be used in identity identification, electronic tag, checkout payment, anti-theft and so on. For example, Japan's Rosen convenience store has started to promote the Reji Robo automatic checkout machine in some stores. Customers put the goods with RFID tags into a special shopping basket, and the cashier can quickly sense the price of the goods. Customers can choose to pay automatically in cash or credit card. After checking out, the bottom of the shopping basket will automatically open and the goods will fall into the bag below. From checkout to bagging, there is no need for clerk service at all. The whole process takes only 15 seconds.
At present, the market has doubts about RFID tags, that is, the unit price cost is much higher than that of printed bar codes, and it still needs manpower to paste or recycle the tags. It seems that it is not cost-effective for commodities with low unit price. In this regard, the personnel of Yuanwang Valley company proposed that RFID tags should be made together from the commodity manufacturing end like bar codes, which can not only reduce costs, but also save manpower. It is suggested that at present, RFID tags and printed bar codes can be used at the same time. For commodities with low price, such as beverages, bar codes will still be used in the near future; Products with medium and high prices, such as clothing, will use RFID tags, which will meet the ideal promotion scenario, save manpower and accelerate the automation process.
For the future development of RFID in unmanned stores, the market is quite optimistic. With the development of industrial 4.0 intelligent manufacturing and the new retail era, it will inevitably drive the decline of RFID cost, and RFID can be applied in multiple categories, which will be more popular in the future.
