rfid electronic tags are closely related to our lives. Security, clothing, wine, schools, tickets, mobile phones and other industries are widely used. But many people still don’t know what an rfid electronic tag is. I will share it with you in the following editor.Rfid electronic tag is the abbreviation of (Radio Frequency Identification), also known as radio frequency identification, commonly known as electronic tag.Definition of rfid electronic labelRadio Frequency Identification (RFID) is a wireless communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets.Many industries have used radio frequency identification technology. By attaching the label to a car in production, the factory can easily track the progress of the car on the production line. The warehouse can track the location of medicines. RFID tags can also be attached to livestock and pets to facilitate the positive identification of livestock and pets (positive identification means to prevent several livestock from using the same identity). Radio frequency identification identification cards allow employees to enter locked parts of the building, and radio frequency transponders on cars can also be used to collect fees for toll roads and parking lots.Some radio frequency tags are attached to clothing, personal belongings, and even implanted in the human body. Since this technology may read personal information without my permission, this technology will also have the risk of infringing on personal privacy.The concept of rfid electronic tagsConceptually, RFID is similar to barcode scanning. For barcode technology, it attaches the encoded barcode to the target and uses a dedicated scanning reader to use optical signals to transfer information from the bar magnet to the scanning and reading Writer; and RFID uses a dedicated RFID reader and a dedicated RFID tag that can be attached to the target, and uses frequency signals to transmit information from the RFID tag to the RFID reader.The development of rfid electronic tagsInitially in the technical field, a transponder refers to an electronic module that can transmit information and reply information. In recent years, due to the rapid development of radio frequency technology, transponders have gained new terms and meanings, and are also called smart tags or tags. The reader of the RFID electronic tag performs wireless communication with the RFID electronic tag through an antenna, and can read or write the tag identification code and memory data. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is quick and convenient.In the future, the rapid development of RFID technology is of great significance to the progress of the Internet of Things.Component of rfid electronic tagTransponder: It is composed of antenna, coupling element and chip. Generally speaking, tags are used as transponders. Each tag has a unique electronic code and is attached to an object to identify the target object.Reader: It is composed of an antenna, a coupling element, and a chip. It is a device that reads (and sometimes writes) tag information. It can be designed as a handheld rfid reader or a fixed reader.Application software system: It is application layer software, mainly to further process the collected data and make it available to people.
