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 the specific targets. A complete RFID system is composed of a reader, an electronic tag, a so-called transponder, and an application software system. The working principle is that the Reader transmits radio frequency energy of a specific frequency, which is used to drive the circuit to send out the internal data. At this point, the Reader receives the interpretati

With the rapid development of science and technology, the security technology is also constantly upgraded. The application of RFID technology in the access control system not only promotes the technical innovation of the access control system, but also promotes the open development of the access control system. RFID electronic tag card, RFID card is cheap, easy to use, high security and can be well managed with a database, its cost performance is very high, and it has a good prospect for promotion. The rapid development of RFID technology, the diversification of RFID products in various fre

RFID Development History: RFID directly inherits the concept of radar and develops a new technology of AIDC, which is vigorous and vigorous. In 1948, Harry Stockman published "Communication Using Reflective Power" which laid the theoretical foundation of RFID. 1) The history of the development of RFID technology. In the 20th century, the theory and application of radio technology is one of the most important achievements in the development of science and technology. The development of RFID technology can be divided into the following 10 years: 1941-1950. The improvement and applic

1. What is RFID RFID is the abbreviation of Radio Frequency Identification, that is, Radio Frequency Identification. It is often called induction chip or proximity card, induction card, contactless card, electronic label, electronic bar code, etc. A complete RFID system is composed of Reader and Transponder. Its action principle is that Reader transmits an infinite wave energy of a specific frequency to Transponder to drive the Transponder circuit to send out the internal ID Code, and then Reader receives the ID Code. Transponder is special in that it is battery-free, contactless and card-fr
