1301792253 application field and working principle

High-frequency identification technology (RFID) is composed of radio-frequency technology, computer processing technology, data processing technology, electronic data processing technology, wireless communication technology and antennas. It is a technology that uses non-contact automatic identification of certain objects through radio frequency signals, rapidly implementing the data acquisition of each object, and real-time transmission of information to the computer.The application of RFID technology eliminates the need for contact with the objects to be identified, thus increasing the reliability, speed and efficiency of data acquisition. The real-time non-contact automatic identification of RFID technology has a wide application in the field of modern logistics and industrial production.

Application Field

RFID technology has been widely used in many fields, mainly including the following four aspects:

• Product anti-counterfeiting and packaging traceability: RFID is used to store product anti-counterfeiting information to distinguish between genuine and fake goods.
• Industrial field: RFID is used to track workpieces in all processes of industrial production, reduce human input frequency and greatly improve production efficiency.
• Transportation and warehousing: RFID is used as a practical means to store information, improve the automatic control of transportation links, and realize the efficient automation of warehousing.
• Retail industry: RFID is used to efficiently check out goods, reduce repetitive writing of data, improve sales efficiency and realize seamless connection between physical merchandise and information.

Working Principle

RFID technology mainly includes tag, reader and antenna. The antenna of the reader searches for the signal from the tag, and the reader sends a radio frequency to power the tag. When the signal is returned to the reader, the tag sends data back to the reader through the signal. The reader stores the data, generates an alarm when needed, and then forwards the collected data to the computer.

An RFID tag consists of the following parts: integrated circuit, antenna circuit, inlay, material, chip and antenna. The integrated circuit is the core component of an RFID tag, which is composed of ROM, RAM, EEPROM, communication interface and microprocessor. The antenna circuit receives the radio frequency signal sent by the reader, and then transmits the response signalis to the reader. The inlay includes a chip and an antenna, which is connected and embedded into the product or packaging material.

In general, RFID technology is a kind of recognition technology with radio frequency signals as transmission carrier. This technology can rapidly obtain information, and has certain stability and sensitivity. It has low cost, fast transmission speed and wide application field. It can be used in many fields and has great application value.
