Introduction to RFID:
Radio frequency identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, 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 the need to establish mechanical or optical contact between the identification system and specific targets.
Radio frequency is generally microwave, 1-100GHz, suitable for short-distance identification communication.
RFID readers are also divided into mobile and fixed types. At present, RFID technology is widely used, such as libraries, access control systems, and food safety traceability.
Technology development process
1940-1950: The improvement and application of radar gave birth to radio frequency identification technology. In 1948, the theoretical foundation of radio frequency identification technology was laid.
1950-1960: The exploratory stage of early radio frequency identification technology, mainly in laboratory experimental research.
1960-1970: The theory of radio frequency identification technology has been developed, and some application attempts have begun.
1970-1980: Radio frequency identification technology and product research and development were in a period of great development, and various radio frequency identification technology tests were accelerated. Some of the earliest radio frequency identification applications appeared.
1980-1990: Radio frequency identification technology and products entered the commercial application stage, and applications of various scales began to appear.
1990-2000: The standardization of radio frequency identification technology has received increasing attention, radio frequency identification products have been widely adopted, and radio frequency identification products have gradually become a part of people's lives.
After 2000: Standardization issues have become more and more important to people, and the types of radio frequency identification products have become more abundant. Active electronic tags, passive electronic tags and semi-passive electronic tags have all been developed. The cost of electronic tags has continued to decrease, and the scale of application industries has expanded.
Radio Frequency Identification:
The theory of RFID technology has been enriched and improved. Single-chip electronic tags, multi-electronic tag reading, wireless readable and writable, long-distance identification of passive electronic tags, and radio frequency identification technology and products that adapt to high-speed moving objects are becoming reality and moving towards application.
