Swiping code into the door, brushing the face into the door, brushing the palm vein into the door, sweeping code payment, IC tag + RFID (radio frequency identification) payment, user behavior analysis payment, etc., behind the unmanned store is a powerful material and technology in support - RF Identify RFID technology. For the entire Internet of Things industry, RFID is one of the most important technologies in many data collection methods, and RFID technology must be represented by actual projects, and in depth with the Internet, big data, artificial intelligence, and cloud computing. Convergence, following the application of large-scale unmanned supermarkets, no one retail led a new round of RFID technology innovation and application. At present, unmanned retail stores can be broadly divided into two genres in terms of technology. They are front-line schools represented by AmazonGo, Amoy Coffee, and take go. All three use cutting-edge technologies such as machine vision and deep learning algorithms. , sensor fusion technology, convolutional neural networks, biometrics, etc.; RFID, represented by Box 7-11, Lawson Japan's unmanned shop, RFID has advantages in the identification and security of cargo, and technology It is also more mature. According to the “2018-2022 Market Survey of China's RFID Industry Market Survey and Investment Prospects Analysis Report†published by the New Thought Industry Research Center, the difference between RFID and traditional barcodes is that, in the course of RFID, electromagnetic signals depend on RF transmission. The terminal recognizes the digital electrical signal converted to the baseband through radio frequency; the traditional barcode, the transmission process mainly relies on the image-related optical signal, and the terminal obtains the digital electrical signal through the photoelectric conversion device. RFID is currently the most suitable technology to be applied to the packaging of unmanned shop goods. However, it also has the disadvantage of high cost, so it is more suitable for high-value goods. If the cost of RFID chips is reduced in the future, then cheap goods can also be used. RFID The application will be more extensive. Differences and advantages of RFID tags and QR codes/bar codes Advantages of RFID technology have obvious future prospects However, there are limitations in the application of RFID tags. RFID has many non-affinity media and cannot be applied to the packaging of metal, liquid, and internal aluminum foils. The liquids are also misunderstood because of absorbing waves. In addition, RFID is vulnerable to shielding. Adhesion is troublesome, easy to tear, and the size and sensing distance are not easily coordinated. Xinsijie industry researcher pointed out that from the perspective of the entire industry, the vigorous development of the Internet of Things will inevitably bring a lot of opportunities for RFID applications. In 2016, the market scale of China’s RFID reached 54.27 billion yuan. However, the high cost of RFID is still a major obstacle to this application. Fortunately, no one retail is becoming a popular application for RFID, unmanned supermarkets, unmanned convenience stores, unmanned refrigerators, and unsold containers, regardless of the ultimate Which form succeeds will bring a high-speed growth opportunity for RFID, and its most powerful competitor AI image recognition is still technically mature.
