In Auchan, RT-Mart and other large supermarkets have started to try unmanned shop mode, the domestic retail concern for the unmanned store also boiled boiling water into the general transpiration state. Careful people will find that whether it is Auchan or RT-Mart are introduced this are based on RFID technology, unda-shop equipment, what kind of RFID technology is what RFID in the field of unmanned stores will bring what kind of application Mode? Here for everyone to be a simple little to share. What is RFID? Radio frequency identification (RFID), also known as radio frequency identification, is a communication technology that identifies specific targets and reads and writes relevant data via radio signals without the need to identify the mechanical or optical contact between the system and a particular target . RFID technology originated in the United Kingdom, used in the second world war to distinguish between enemy and aircraft identity, started commercial in the 1960s. RFID technology is an automatic identification technology that is widely used in ID documents, access control, supply chain and inventory tracking, car charging, anti-theft, production control and asset management. After Walmart, Metro and other retail enterprises to use the technology, the development of RFID technology has entered a golden age! Several applications based on RFID technology unattended! Unmanned shop based on RFID technology currently has the following three modes, according to the use of processes to be divided into major: 1, pre-identification (identity) mode 2, free identification (identity) mode 3, full open mode Pre-identification (identity) mode refers to the user when you open the smart cabinet or UAV door need to be identified before the product can be purchased. Such as Auchan introduced unmanned stores, first scan the two-dimensional code (identity authentication) before entering, that is a typical pre-identification (identity) application, if you can not complete the identification, the consumer can not make shopping! Are equipped with RFID tags and form the corresponding electronic bill) Free identity (identity) mode means that users do not need to be identified for product shopping. Generally, such unmanned stores will be equipped with an access control system. Consumers can enter the store directly through physical switches. After the consumers enter, access control locks up automatically. After the purchase is completed and the payment is successful, the door can be reopened. (Goods are equipped with RFID tags, and the formation of the corresponding electronic bill) Full open mode refers to the user can freely access the store, and are free to choose products, goods with RFID and two-dimensional code payment tag, consumers choose the product and scan code to complete the payment after the store. However, if the payment is not completed and the store, the access control system will automatically detect and alarm. The advantage of the full open model is that it can solve the problem of multi-point shopping settlement while the store renovation is relatively controllable. This mode, if equipped with a small number of service personnel and the combination of the first two modes of application equipment, is particularly suitable for convenience stores, supermarkets to form a man, no combination of the new model.
