RFID technology is now widely used in many fields such as logistics, warehousing, retail, manufacturing, military assets inventory, etc., which can greatly help enterprises optimize management and operations. However, in reality, the RFID system may also encounter some problems during operation, among which the most typical one is that the reader cannot read the RFID chip. So what are the common reasons why the RFID reader cannot read the chip?

In daily life, we often see various 1D and 2D codes, from scanning to ordering food to express delivery, from ticketchecking to shopping label scanning and identification, etc. It can be said that 1D and 2D codes have become an indispensable part of modern life, so what are their specific types?

RFID is a type of automatic identification technology that uses wireless radio frequency to conduct non-contact two-way data communication and uses wireless radio frequency to read and write recording media (electronic tags or radio frequency cards) to achieve the purpose of identifying targets and exchanging data. In modern library management, RFID tags are becoming an important tool to improve the efficiency of book tracking and management. Currently, there are mainly the following types of commonly used library electronic tags on the market:

With the development of the economy, the food and beverage processing and production industry has developed rapidly in recent years. Thanks to the application of science and technology, science and technology have not only improved production efficiency, but also improved food production quality and food safety. Among them, RFID (radio frequency identification) technology is more and more widely used in the food industry. Next, let's learn about the application of RFID technology in various links of the food processing industry.

Physical training and assessment of students are the basic requirements for physical exercise. However, for a long time, the difficulty of organizing multi-person training and the tediousness of multi-person assessment have been difficult to solve and long-standing problems. Traditional campus physical examinations rely on manual recording of scores, which is time-consuming and labor-intensive, prone to errors, and the physical examination data is scattered, making it difficult to effectively analyze and use. It is difficult to effectively supervise the physical examination process of students, and there are risks such as substitution and cheating. Students have to wait in line for a long time and the physical examination process is cumbersome. With the development of RFID technology, smart campus physical examination solutions based on RFID technology have begun to be launched. Let's take a look at the content of the solution.

With the rapid development of information technology, traditional manual management has been gradually replaced by digital management, and the use of barcode recognition, computer network and computer software technology has improved management efficiency. However, library management still faces some challenges, such as self-service repayment of books, rapid inventory, search and sorting, which affect the management and service level of the library. In this process, RFID technology combined with intelligent management system for book management has gradually become a new trend.

Ultra-high frequency RFID (UHF RFID, 860-960 MHz) technology is an important branch of the RFID field. Due to its long reading distance, high-speed reading capability and simultaneous reading of multiple tags, it has gradually been widely used in logistics, retail, manufacturing, medical and other industries, changing the management and operation methods of many industries. So what is the development history of UHF technology? Let's take a closer look and look forward to the future development trend.

Recently, Deepseek has become popular around the world and triggered a new wave of AI technology. So what impact does the development of AI have on the Internet of Things (IoT) industry?

5G is a new generation of broadband mobile communication technology with high speed, low latency and large connection characteristics.

The communication standards of radio frequency tags are the basis for tag chip design. The current international communication standards related to RFID mainly include ISO/IEC 18000 standard, ISO11784/ISO11785 standard protocol, ISO/IEC 14443 standard, ISO/IEC 15693 standard, EPC standard, etc.

The working principle of fingerprint recognition mainly includes three functions: reading of fingerprint images, extracting features, and comparing fingerprints. Common fingerprint recognition technologies are: optical, capacitive, and ultrasonic.

According to the regulations of various countries/regions, UHF RFID frequencies are different. From the common UHF RFID frequency bands around the world, the North American frequency band is 902-928MHz, the European frequency band is mainly concentrated in 865-858MHz, and the African frequency band is mainly concentrated in 865-868MHz, the highest frequency band in Japan is 952-954MHz, and the frequency band in South Korea is 910-914MHz. There are two frequency bands in China, Brazil, and South Africa. The frequency bands in China are 920-925MHz and 840-845MHz, and the frequency bands in Brazil are 902-907.5MHz and 915-928MHz. On the whole, the UHF frequency bands in the world are mainly concentrated in 902- 928MHz and within 865-868MHz.

Supply chain management refers to the management and coordination of the entire process from the procurement of raw materials to the delivery of final products to customers. The Internet of Things technology is to exchange data through physical equipment networks, sensors, software and other tools, connect objects and equipment, and realize intelligent interaction and real-time monitoring of information. IoT technology can be well applied in supply chain management to improve the visibility, efficiency and traceability of supply chain processes.

Thingmagic M6e-Micro, adopts ultra-small module structure design, and excellent "fast search algorithm", especially for fast-moving label reading,which can be embedded in a variety of commonly used handheld and portable devices.

The passive electronic price tag is a new type of commodity label based on RFID technology. Compared with the traditional paper price tag, it has higher flexibility and readability, and it has become popular in retail scenes such as shopping malls and supermarkets.

In recent years, RFID technology and products have been widely used in various industries. What is the manufacturing process of RFID chips?
