Radio frequency identification technology is a non-contact automatic identification technology. It is a short-distance wireless communication system composed of electronic tags (Tag/Transponder), readers (Reader/Interrogator) and middleware (Middle-Ware). The tag in radio frequency identification is a combination of radio frequency identification tag chip and tag antenna. Tags are divided into active tags and passive tags according to their working modes. The active tag itself carries a battery to provide it with the energy required for the reader to communicate; the passive tag uses the inductive coupling or backscattering working mode, that is, the electromagnetic field or electromagnetic wave emitted by the…

RFID is a general term for radio frequency identification technology, which is the same as other identification methods such as barcodes and IC cards. Its basic function is to identify the unique identifier (UID) of the target item. The difference is that it uses radio frequency transmission to complete non-contact automatic identification. , and realize the identification of moving targets and multi-targets. RFID is also a data communication technology. It has the basic functions of the basic components of the communication system, such as sending, receiving and channeling, and transmitting information. The difference is that the information it transmits is…

Aiming at the problems that the existing car access control system and tire pressure monitoring system are independent of each other, hardware redundancy and high production cost, a design scheme of car security anti-theft system based on radio frequency identification technology is proposed. In terms of radio frequency communication, the system uses the combination of 434 MHz UHF frequency band and 125 kHz LF frequency band to realize the functions of system tire pressure monitoring, remote control door lock and engine anti-theft lock. Automobile security and anti-theft system based on RFID technology Radio Frequency Identification (RFID) is a non-contact automatic…

In recent years, due to the continuous deepening of people’s understanding of RFID technology and the continuous reduction of application costs, RFID has continued to accelerate its penetration in various industries. In the clothing industry, Uniqlo, Decathlon, H&M, Heilan House and other big-name shoe and apparel manufacturers have applied RFID on a large scale to improve the efficiency of the supply chain; libraries all over the country choose to use RFID solutions to manage massive books, and Various forms of products such as librarian workstations, self-service book return boxes (machines), mobile inventory vehicles, sorting machines, etc.; airlines use RFID technology…
