How to understand RFID technology in seconds depends on these three aspects!

  First of all, RFID technology, also known as radio frequency identification, is a communication technology that uses radio signals to identify specific targets and read and write related data, without the need to establish mechanical or optical contact between the identification system and specific targets. The rapid development of RFID technology is of great significance to the progress of the Internet of Things. Why our express delivery can always be accurate on the route? Why is the huge amount of books in the school library organized in a neat and orderly manner? Why can some accidentally stolen items be traced back quickly? And these have to use RFID technology, because in this era of the Internet of Things, it is one of the key technologies for data connection and data communication.

  What is RFID technology? RFID, also known as radio frequency identification, uses radio signals to identify and read and write specific target data. It does not require mechanical contact or a specific complex environment to complete the identification and read and write data. Nowadays, the application of RFID technology that everyone talks about is actually an RFID tag, which already exists in every aspect of our lives. It works in two situations. One is that when the RFID tag enters the effective recognition range of the reader, it receives the radio frequency signal sent by the reader, and uses the energy obtained by the induced current to send out the information stored in the chip, and the other is The RFID tag actively sends a signal of a certain frequency, the reader receives and decodes the information, and then sends it to the central information system for relevant data processing. In the middle of the twentieth century, based on the improvement and application of radar, radio frequency identification technology began to lay the foundation, and then began its initial development. Until today, the application of RFID technology has a history of more than half a century. At present, RFID technology is in China. The development status of foreign countries is good, especially the United States, Germany, Sweden, Japan, South Africa, the United Kingdom and Switzerland have relatively mature and advanced RFID systems. The development of RFID is also advancing rapidly. The more successful cases are Launched a completely independent research and long-distance automatic identification system.
