What RF stands for in wireless is radio frequency identification technology, which is an abbreviation for Radio Frequency Identification.
The principle of RFID is to realize the target recognition through the non-contact data communication between the reader and the tag. At present, the typical applications of RFID are animal chip, car chip anti-theft device, access control, parking lot control, production line automation and so on.
Through the combination of wireless communication and data access technology, and then connected to the database system to achieve non-contact two-way communication, so as to achieve the purpose of identification, data exchange, and a very complex system in series. In the recognition system, through the electromagnetic wave to realize the electronic label read-write and communication.
Extended information
In terms of its external performance, the carrier of radio frequency identification technology is generally waterproof, anti-magnetic, high temperature resistant to ensure that the radio frequency identification technology in the application of stability. As far as its use is concerned, radio frequency identification has advantages in real-time data updating, information storage, service life, work efficiency, security and so on.
RFID technology in the computer-based storage information, up to several megabytes, can store a large amount of information, to ensure the smooth operation of the work. RFID technology has a long service life, as long as the staff pay attention to protection, it can be reused.
