On April 25, the home appliance giant Hisense officially released the world’s first global RFID food management refrigerator. For the first time, RFID technology was used in refrigerator products to identify and manage food materials in the refrigerator, freezer, and greenhouse, making refrigerators powerful. The ability of food management.

Compared with other innovations, this refrigerator product of Hisense directly hits the consumption pain points of food management and preservation, and introduces RFID technology for the first time, which brings a refreshing feeling to people. At the Hisense Food Refrigerator Conference, Feng Tao, Executive Vice President of Hisense Refrigerator, said, “Before that, everyone paid too much attention to hardware+ and concentrated a lot of development resources on the hardware. It did not further solve the pain points of consumer food management and preservation. “By introducing RFID technology, this refrigerator can automatically identify the type, time and location of stored food. This is not only a major innovation in refrigerator products, it also further expands the application scenarios of RFID technology.
What is the magical RFID technology?
The English full name of RFID is Radio Frequency Identification, which is literally translated as Radio Frequency Identification, and is considered to be one of the top ten important technologies in the 21st century. The RFID system uses electronic tags to mark objects. The tags contain chips and antennas, and then use RFID readers to send and receive data. Compared with image recognition technology, RFID technology has inherent advantages such as obstacle recognition, strong penetrability, batch reading of data, and long service life.
At present, RFID has been widely used in various industries, such as warehousing and logistics, shoes and clothing, retail, smart manufacturing, anti-counterfeiting traceability, transportation, medical treatment, book management, asset management, aviation, etc., and constantly develops new application scenarios . International retail giants such as Wal-Mart and Metro have used RFID supply chain management technology. Apparel brands such as Decathlon, Uniqlo, and Hailan House have also introduced RFID technology in their global stores for clothing management, control and scheduling, etc., while improving operational efficiency. It also effectively solves the problem of product anti-counterfeiting.
What other applications of RFID in home appliances?
In addition to the application in smart refrigerators, the application of RFID in home appliances can go far beyond that.
As early as 2012, NXP launched a smart washing machine solution using RFID and NFC technology at an exhibition in Germany. After using this solution, the washing machine can automatically detect the color and texture of the clothes from the buttons of the built-in RFID tags, and optimize the washing program according to the characteristics of the clothes and detergent. On the mobile phone with NFC function, you can also remotely control the smart washing machine and change the working mode or status of the washing machine.
Haier, a well-known domestic appliance company, is also vigorously promoting the application of RFID in the laundry industry. In 2017, Haier washing machines and related clothing and home textile industries jointly issued RFID clothing identification standards. This standard is the first standard for the washing and care industry, and even the clothing and home textile industry. With a unified RFID clothing identification standard, buying clothes with RFID identification standards can be thrown directly into the washing machine to automatically match the washing program, and then realize true intelligent washing and care.
With the continuous improvement of people’s living standards and health awareness, there are also higher requirements for the home environment. Many families have added air purifiers and water purifiers, and filter elements and filters need to be replaced after a certain period of time. The Mijia air purifier launched by Xiaomi is equipped with an RFID chip, which can be used to record and read information such as the use time of the filter element. Installing RFID electronic tags with anti-counterfeiting keys on filter elements and filters can achieve effective anti-counterfeiting traceability. Using an algorithm-based two-way authentication mechanism, one core and one secret, which can never be read, ensure that RFID tags cannot be cloned. Ordinary consumers can use a mobile phone with NFC function to check the filter element and filter online, and prevent suppliers or distributors in different regions from collaborating with each other.

In 2009, Sony released two TVs with built-in FeliCa RFID tag readers. When users are watching TV commercials, if they want to buy the goods mentioned in them, they can directly use their mobile phones or other multimedia devices that support RFID technology to pay.
At the 2010 China International Consumer Electronics Fair, Haier released the world’s first TV remote control using RFID radio frequency identification technology. Unlike the usual infrared remote control, this remote control is non-directional, and the user can remotely control the TV from any angle. This remote control can remotely control the TV through the wall, with high sensitivity and fast response speed, which greatly reflects the flexibility of the user’s operation; in addition, the power consumption of the RFID radio frequency remote control is extremely low, which is only 1/30 of the ordinary infrared remote control. It greatly reduces the amount of battery used, and while providing convenience for users, it also conforms to the concept of low carbon and environmental protection.
RFID injects greater imagination into home appliances
Nowadays, all kinds of home appliances have become the standard configuration of households, which are closely related to the living standards of residents. According to the “Report on China’s Home Appliance Market in 2019” released by the China Electronics Information Industry Development Research Institute, the retail sales of my country’s home appliance market in 2019 has reached 891 billion yuan, a year-on-year increase of about 10%. In the face of huge market demand and fierce competition, home appliance companies want to enhance their market competitiveness, they need to continuously promote product innovation, and the combination with RFID technology is an excellent development direction.
As more and more smart phones are equipped with NFC functions, many home appliances have begun to communicate with mobile phones, and then realize some new functions, including product anti-counterfeiting traceability, remote control, status monitoring, and so on. From the perspective of this trend, RFID helps to integrate home appliances into the smart home system faster.
Through the analysis of the above-mentioned home appliance cases, it is not difficult to find that these applications are often tailor-made according to the product characteristics of home appliances and possess a certain spirit of innovation. Different home appliances correspond to different application scenarios, and the functions realized after the introduction of RFID technology are also quite different. For the combination of RFID technology and home appliance products, in addition to the in-depth exploration of technology, it also tests the imagination of the company’s product form evolution.
