3. Electronic tags
Electronic tags are also called radio frequency tags, transponders and data carriers; Readers are also called reading devices, scanners, reading heads, communicators and readers (depending on whether electronic tags can rewrite data wirelessly). Spatial (non-contact) coupling of radio frequency signals between the electronic tag and the reader is realized by coupling elements; In the coupling channel, energy transfer and data exchange are realized according to the time sequence relationship.
Electronic tag is a tool to improve the efficiency and accuracy of identification, and this technology will completely replace bar code. RFID radio frequency identification is a non-contact automatic identification technology, which can automatically identify the target object and obtain relevant data through radio frequency signals, and can work in various harsh environments without manual intervention. RFID technology can identify high-speed moving objects and multiple tags at the same time, which is quick and convenient to operate. RFID tag is a breakthrough technology: "First, it can identify a single very specific object, instead of only identifying one type of object like bar code;": Secondly, it uses radio frequency, which can read data through external materials, while barcode must rely on laser to read information; Third, multiple objects can be read at the same time, while barcodes can only be read one by one. In addition, the amount of information stored is also very large. "
