RFID is the abbreviation of Radio Frequency IdenTIficaTIon, namely radio frequency identification. Often referred to as inductive electronic chips or proximity cards, proximity cards, contactless cards, electronic tags, electronic bar codes, and the like.
A complete RFID system consists of two parts, Reader and Transponder. The principle of operation is that the Reader transmits a certain frequency of infinite wave energy to the Transponder, which is used to drive the Transponder circuit to send the internal ID code. At this time, the Reader receives the ID. Code. Transponder's speciality is that it is free of battery, contact-free, and free of card, so it is not afraid of dirt, and the chip password is the only one in the world that cannot be copied, with high safety and long life.
The application of RFID is very extensive. At present, typical applications include animal wafers, automobile chip alarms, access control, parking lot control, production line automation, and material management. There are two types of RFID tags: active tags and passive tags.
2. What is RFID technology?RFID radio frequency identification is a non-contact automatic identification technology. It automatically recognizes the target object and acquires relevant data through the radio frequency signal. The identification work can work in various harsh environments without manual intervention. RFID technology can recognize high-speed moving objects and recognize multiple labels at the same time, which is quick and easy to operate.
Short-range RF products are not afraid of harsh environments such as oil stains and dust pollution. Bar codes can be replaced in such environments, such as tracking objects on the assembly line of a factory. Long-range RF products are mostly used for transportation, and the recognition distance can reach several tens of meters, such as automatic charging or identification of vehicle identity.
3. What is an RFID solution?The RFID solution is an RFID application solution developed by RFID technology providers for the development characteristics of the industry. It can be tailored to the actual requirements of different enterprises.
RFID solutions can be classified according to industry, logistics, anti-counterfeiting, identification, asset management, animal management, fast payment, etc. Click here for the solution.
4. The basic components of RFIDThe most basic RFID system consists of three parts:
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;
Reader: A device that reads (and sometimes writes) tag information and can be designed to be handheld or fixed;
Antenna: Transmits RF signals between the tag and the reader.
5. RFID development process:RFID directly inherits the concept of radar and has developed a new AIDC technology called RFID technology. In 1948, Harry Stokeman's "Communication with Reflected Power" laid the theoretical foundation for RFID.
1) The history of the development of RFID technology. In the 20th century, the theoretical and applied research of radio technology was one of the most important achievements in the development of science and technology. The development of RFID technology can be divided into the following ten years:
From 1941 to 1950. The improvement and application of radar gave birth to RFID technology, and in 1948 laid the theoretical foundation of RFID technology.
1951 - 1960. The exploration phase of early RFID technology is mainly in laboratory experimental research.
1961—1970. The theory of RFID technology has been developed and some application attempts have begun.
1971-1980. RFID technology and product development are in a period of great development, and various RFID technology tests are accelerated. Some of the earliest RFID applications have emerged.
1981-1990. RFID technology and products entered the commercial application stage, and applications of various scales began to appear.
1991-2000. The standardization of RFID technology is getting more and more attention, RFID products are widely used, and RFID products are gradually becoming a part of people's lives.
2001-present. Standardization issues are increasingly valued by people, and RFID products are more abundant, active electronic tags,
Both passive electronic tags and semi-passive electronic tags have been developed, the cost of electronic tags has been continuously reduced, and the scale application industry has expanded.
The theory of RFID technology is enriched and improved. Single-chip electronic tags, multi-electronic tag reading, wireless readable and writable, long-distance identification of passive electronic tags, and RFID for high-speed moving objects are becoming a reality.

8, asset management: various types of assets (precious or large number of similarities or dangerous goods, etc.)
9, transportation: high-speed no parking, taxi management, bus hub management, railway locomotive identification, etc.
10, food: fruit, vegetables, fresh, food and other freshness management
11. Animal identification: Identification and management of animal husbandry, animal husbandry, pets, etc.
12. Library: Bookstore, library, publishing house, etc.

14. Aviation: Manufacturing, passenger tickets, baggage tracking
15. Military: Identification and tracking of ammunition, guns, supplies, personnel, trucks, etc.
Draw-wire sensors of the wire sensor series measure with high linearity across the entire measuring range and are used for distance and position measurements of 100mm up to 20,000mm. Draw-wire sensors from LANDER are ideal for integration and subsequent assembly in serial OEM applications, e.g., in medical devices, lifts, conveyors and automotive engineering.
