The hottest black technology in unmanned retail: RFID technology

　　Speaking of recent hot topics, "unmanned retail stores" are one of them. Since the end of last year, Amazon launched the first unmanned physical supermarket Amazon Go, and major companies such as Alibaba, JD.com, RT-Mart and others have joined in, and unmanned stores have been pushed to the forefront.

　　The actual landing of unmanned stores relies on black technology, including FRID technology.

　　What is FRID technology?

　　Radio Frequency Identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, is a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets .

　　RFID technology first originated in the United Kingdom and was used in the identification of enemy and friendly aircraft in World War II. Commercial use began in the 1960s. After Walmart, Metro and other retail companies applied this technology, the development of RFID technology has also entered a golden age.

　　Several application modes of unmanned stores based on RFID technology:

　　1. Pre-identification (identity) mode Pre-identification (identity) mode: refers to that the user needs to perform identity recognition before opening the smart commodity cabinet or the door of an unmanned store before shopping. (The goods are equipped with RFID tags and form corresponding electronic bills)

　　2. Recognition-free (identity) mode Recognition-free (identity) mode: refers to users who do not need to perform identity recognition to purchase goods. Generally, such unmanned stores will have an access control system, and consumers can directly enter the store through a physical switch. After the consumer enters, the door is automatically locked, and the door can be reopened after the consumer completes the purchase and the payment is successful. (The goods are equipped with RFID tags and form corresponding electronic bills)

　　3. Fully open mode Fully open mode: refers to users who can freely enter and exit the store, and can freely choose goods. The goods are equipped with RFID and QR code payment tags. Consumers can leave the store after selecting the goods and scanning the code to complete the payment. However, if you leave the shop without completing the payment, the access control system will automatically monitor 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.

　　RFID technology is everywhere

　　In addition to the unmanned retail industry, RFID technology is also widely used in many fields including channel management, data collection and identification systems, positioning systems, smart campuses, and smart transportation.

　　Our common access control, library management, and no-charge parking lot management systems belong to channel management; ID card identification systems, consumption management systems, social security cards, bank cards, and attendance systems belong to data collection and management; museum positioning, prisons Personnel positioning, mine personnel positioning, production line automation management, terminal item management, etc. are all positioning systems.

　　Advantages of RFID technology:

　　RFID is a flexible application technology that is easy to control, simple and practical, and especially suitable for automatic control. Can work freely in various harsh environments.

　　RFID technology has the advantages of absolute anti-counterfeiting, encryption technology, no reuse, full traceability, information control, etc., which can better reduce labor costs, improve work efficiency, reduce investment in anti-counterfeiting, and improve product quality.

　　With economic development and technological progress, the application of RFID technology in all walks of life will become more and more extensive. In the construction of the Internet of Things based on RFID technology, governments of all countries are aware of the impact of RFID technology on the future and the huge business opportunities contained therein, and actively promote the development of the RFID industry.
