RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification. Commonly referred to as inductive electronic chip or proximity card, inductive card, non-contact card, electronic label, electronic barcode, etc. A complete RFID system is composed of Reader and Transponder. Its operating principle is that Reader transmits an infinite electric wave energy of a specific frequency to Transponder, which is used to drive Transponder circuit to send out the internal ID Code. Reader then receives this ID. Code. Transponder is special in that it is battery-free, contact-free, and card-free so it is not afraid of dirt, and the chip password is the only one in the world that cannot be copied, with high security and long life.
The application of RFID is very extensive. At present, typical applications include animal chips, car chip anti-theft devices, access control, parking lot control, production line automation, and material management. There are two types of RFID tags: active tags and passive tags.
2. What is an electronic label
Electronic tags are RFID, and some are called radio frequency tags and radio frequency identification. It is a non-contact automatic identification technology. It uses radio frequency signals to identify target objects and obtain relevant data. The identification work does not require human intervention. As a wireless version of the barcode, RFID technology has waterproof, antimagnetic, high temperature resistance, which is not available in barcodes. It has the advantages of long service life, large reading distance, encryption of data on the label, greater storage data capacity, and free storage information change.
3. What is RFID technology
RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work does not require human intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can recognize multiple tags at the same time, and the operation is quick and convenient.
Short-range RF products are not afraid of harsh environments such as oil stains and dust pollution. They can replace barcodes in such environments, for example, they are used to track objects on the factory's assembly line.
Long-distance RF products are mostly used in traffic, and the recognition distance can reach tens of meters, such as automatic toll collection or vehicle identification.
