RFID is the radio frequency identification technology that carries on the non-contact data communication between the reader and the tag to achieve the identification target. Radio frequency identification (RFID) tags consist of microchips and radio antennas that store unique data and transmit it to RFID readers. They use electromagnetic fields to identify and track objects. RFID tags come in two forms, active and passive. Active tags have their own power source to transmit their data. Unlike passive tags, passive tags need a nearby reader to emit electromagnetic waves and receive the energy of the electromagnetic waves to activate the passive tag, and then the passive tag can transmit the stored information to the reader.
Radio frequency identification technology through radio waves do not contact fast information exchange and storage technology, through wireless communication combined with data access technology, and then connected to the database system, to achieve the purpose of non-contact two-way communication, to achieve the purpose of identification, used for data exchange, series up a very complex system. In the recognition system, the reading, writing and communication of electronic tags are realized by electromagnetic wave.
RFID applications are very wide, the current typical applications are animal chip, automotive chip anti-theft device, access control, parking lot control, production line automation, material management, goods labeling, etc.
In real life, we can often see RFID labels in various product packaging, such as supermarket, RFID labels in clothing, shoes, bags and other products, why this situation? Let’s first understand the advantages of RFID tags and reading and writing devices.
1.RFID tags and readers have a long reading distance (1-15M).
2. Multiple labels can be read at a time, and the data collection speed is fast.
3. High data security, encryption, update.
4.RFID tags can ensure the authenticity of products, with the function of anti-counterfeiting traceability.
5.RFID electronic tags are generally waterproof, antimagnetic, high temperature resistance and other characteristics, to ensure the stability of the application of radio frequency identification technology.
6.RFID technology can store information according to computers, up to several megabytes, and can store a large amount of information to ensure smooth work.
