Comparison of RFID, visual recognition, and gravity sensing unmanned vending cabinets

Unmanned containers have become a new retail explosion point with efficient operation and reduction of cargo damage. At present, the mainstream identification technologies in the industry include the following: RFID (Radio Frequency Identification): RFID technology that uses electronic tags as a medium has a fatal defect: when the tag is damaged Or the user can get the product for free when it is torn off by the user. It is difficult to sense in thunderstorm and liquid tank. If it is a box of biscuits, the user can open the box and only take the biscuits inside, and leave the RFID-tagged box inside, so that they can enjoy it for free. With reference to the malicious use of shared bicycles, once a large number of unmanned containers are placed in public places, they will definitely be used maliciously. It is understood that the cost of each RFID product barcode is 0.5 yuan, which means that as long as RFID technology is used, the cost of each product in the unmanned convenience store will be 0.5 yuan more. At the same time, attaching electronic tags to each product will consume huge labor costs, and an RFID cabinet will cost tens of thousands of yuan. Visual recognition: The disadvantage of this technology is that when the user is shopping, the calculation speed of the recognition system is significantly slower, and there is even the possibility of error. At the same time, this technology has strict restrictions on the size, placement, height, and lighting of the products, and the categories of supported products are also limited. Gravity sensing: Gravity sensor technology uses sensors to sense the weight change on the shelf to detect the behavior of goods being taken or put back. The only drawback of gravity sensing is that equal replacement cannot be identified. The accuracy of the gravity sensor unmanned vending container can reach 0.5g, and the error range of the goods can be set in the background, and you can choose to sell fresh food by catty or sell food and beverage by piece. There are models for freezing, refrigerating, heating, and room temperature, which can be customized according to the different needs of customers. More than 3,000 models of gravity-sensing unmanned vending containers have been installed in more than 50 key cities across the country. We sincerely invite all partners to work hand in hand to create brilliant! Previous post: What are the types of vending cabinets?
