Talking about the application of RFID technology in unmanned convenience stores

　　There are many unmanned convenience stores, but they are basically inseparable from RFID technology. At present, one category of unmanned convenience stores is traditional retail led by Auchan, RT-Mart, and Rainbow, the other category is Internet companies represented by Ali and Bingo Box, and the other category is represented by Jiaranzhijia and Wahaha. Cross-border operating companies. What they have in common is that they are basically inseparable from RFID technology. RFID tags are affixed to each product for checkout and collection. In addition, it is equipped with a monitoring system, remote customer service and other functions.

　　Unmanned shops based on RFID technology can be divided into the following three modes according to the use process: 1. Pre-identification (identity) mode; 2. Identification-free (identity) mode; 3. Fully open mode

　　The pre-identification (identity) mode means that the user needs to perform identity identification before opening the smart merchandise cabinet or unmanned store door before shopping. For example, the unmanned store introduced by Auchan must scan the QR code (identity authentication) before entering, which is a typical pre-identification (identity) application. If the identification cannot be completed, the consumer cannot make a shopping action! Equipped with RFID tags and form corresponding electronic bills)

　　The identification-free (identity) mode means that users can purchase goods without identification. Generally, such unmanned stores will have an access control system. Consumers can directly enter the store through a physical switch. After the consumer enters, the access control is automatically locked. After the consumer completes the shopping and the payment is successful, the access control can be reopened. (The goods are equipped with RFID tags and form corresponding electronic bills)

　　The fully open mode means that users can freely enter and exit the store, and can freely choose products. The products have RFID and QR code payment tags. Consumers can leave the store after selecting products and scanning the code to complete the payment. However, if you leave the shop without completing the payment, the access control system will automatically detect and alarm. The advantage of the fully open model is that it can solve the multi-point shopping settlement problem, while the store transformation is relatively controllable. If this mode is equipped with a small number of service personnel and combined with the application equipment combination of the first two modes, it is particularly suitable for convenience stores and supermarkets to form a new mode of combined application of manned and unmanned.

　　The retail industry itself has meager profits, especially in the convenience store scene, where the unit price of goods is generally not high, and any increase in cost will pose a huge challenge to its profitability. One aspect of RFID solutions that has always been criticized is the high cost. However, in recent years, as technology development and application scenarios increase, the cost of RFID tags has declined. However, UHF RFID is more popular because of its remarkable characteristics, such as high sensitivity, the fastest data collection speed, the number of multiple tags, and low cost.

　　In addition, the full participation of RFID in unmanned retail/smart retail also urgently needs to solve many important issues such as recognition rate, system-level product standardization, material damage and continuous research and development. Some professionals pointed out that RFID, artificial intelligence and big data, these three will become important factors to promote or restrict the realization of smart retail in the future.
