What is RFID technology? RFID radio frequency identification is a non-contact automatic identification technology, which can automatically identify the target object and obtain relevant data through radio frequency signals, and can work in various harsh environments without manual intervention. RFID technology can identify high-speed moving objects and multiple tags at the same time, and C is fast and convenient.
What are the basic components of RFID?
Tag: It is composed of coupling elements and chips, and each tag has a unique electronic code, which is attached to the object to identify the target object;
Reader: a device for reading (sometimes writing) tag information, which can be designed as a handheld or fixed device;
Antenna: It transmits radio frequency signals between the tag and the reader.
The basic working principle of RFID technology: after the tag enters the magnetic field, it receives the RF signal sent by the reader, and uses the energy obtained by the induced current to send out the product information stored in the chip (passive tag, passive tag), or actively sends out a signal with a certain frequency (active tag, active tag); The reader reads and decodes the information and sends it to the central information system for data processing.

What makes retailers admire RFID so much?
According to the retail analyst of Sanford C. Bernstein, Wal-Mart can save $8.35 billion a year by adopting RFID, most of which is due to the labor cost saved by not having to manually check the bar codes of purchased goods. Although other analysts think that the figure of $8 billion is too optimistic, there is no doubt that RFID can help solve the two biggest problems in the retail industry: commodity shortage and loss (products lost due to theft and supply chain interruption). Now, Wal-Mart loses almost $2 billion a year. If a legitimate enterprise can reach this figure, it can rank 694th in the ranking of the largest enterprises in the United States 1000. Research institutions estimate that this RFID technology can help reduce theft and inventory levels by 25%.
