Radio Frequency Identification (RFID) technology refers to the transmission of data between RFID tags and RFID readers through remote wireless means. With the development of technology, RFID technology is being used in more and more applications and continues to grow rapidly.

Basic components of an RFID system: An RFID system consists of three parts: RFID tags or smart labels, RFID readers, and antennas.

Principle of RFID communication: RFID tags are used to transmit data to RFID readers, which then convert the radio signals into usable data. The reader transfers the data obtained from the tag to a computer system through a communication interface. The data can be stored in a database for extraction and use when needed. It can also be connected to a smart display for real-time monitoring applications.

RFID systems are mainly classified into three types based on communication frequency: Low Frequency (LF) RFID: LF RFID systems operate in the frequency range of 120-150 kHz, with a short communication range of 0.1 meters and a slower data transmission rate. It is suitable for applications that require low-speed and short-distance communication. High Frequency (HF) RFID: HF RFID systems operate at a frequency of 13.56 MHz, with a communication distance of up to 1 meter. Ultra High Frequency (UHF) RFID: UHF RFID systems operate in the frequency range of 860-960 MHz, with a communication range of up to 12 meters.

Common applications:

  1. Construction industry: In the construction and other related industries, materials are often the most costly part of a project. Applying RFID technology in large construction sites can easily track the location and quantity of materials, ensuring material security.

  2. Aerospace applications: Applying RFID technology in the aerospace industry can simplify supply chain and passenger luggage tracking. In air transportation, whether it is for passengers or cargo, frequent movement of goods on the plane makes real-time monitoring challenging. By placing RFID readers in the cargo hold and attaching electronic tags to all goods, we can monitor the status of goods in real-time.

  3. Healthcare and medical industry: Similar needs exist in the healthcare field. We can monitor drugs in real-time, ensuring accurate information on quantity and preventing loss. RFID tags can also be placed in patient wristbands for doctors to scan and confirm personal and medical record information.

  4. Food industry storage and transportation: Product tracking at the individual quantity level is beneficial to many industries, especially in the retail industry, making it suitable for RFID deployment. We can track goods throughout the supply chain and monitor their transportation status. For example, in self-service vending machines, when a customer opens a cabinet to take out a product, the machine automatically identifies the purchased product and calculates the price, saving the cost of manual sales.

  5. Automotive and bicycle rental industry: RFID technology can be used to detect vehicle returns in shared bike and car rental services. By installing RFID readers at designated parking points, when a bike or car is parked at the designated point, the RFID reader automatically detects the vehicle information and handles the return process. Meanwhile, our backend management personnel can also access the parking information. The application of RFID technology in the automotive and bicycle rental industry can complement GPS and reduce the cost of GPS applications.

With RFID technology being widely applied in various industries, it continues to provide convenience and improve our quality of life.
