Radiofrequency identification (RFID), also known as radio frequency identification (RFID), is a communication technology commonly known as electronic tags. Radio signals can be used to identify specific targets and read and write related data without having to identify mechanical or optical contact between the system and a particular target. For radio frequency, it is usually microwave, 1-100GHz, suitable for short-distance identification communication. RFID readers are also mobile and fixed.
At present, RFID technology is widely used, such as library, access control system, food safety traceability. The component of RFID is Tag (consists of a coupling element and a chip, each tag having a unique electronic code attached to the object to identify the target object and Reader(A device that reads (and sometimes writes) tag information and can be designed to be handheld or fixed) and Antenna(Transmits RF signals between the tag and the reader). According to the application frequency, RFID is divided into low frequency (LF), high frequency (HF), ultra-high frequency (UHF), microwave (MW), and the corresponding representative frequencies are low frequency below 135KHz, high-frequency 13.56MHz, super High-frequency 860M~960MHz, microwave 2.4G, 5.8G.
