RFID technology involves many high-tech fields such as information, manufacturing, materials, etc., covering technologies such as wireless communication, chip design and manufacturing, antenna design and manufacturing, label packaging, system integration, and information security. Some national and international multinational companies are accelerating the development and application of RFID technology. In the past decade, thousands of patents on RFID technology have been produced, mainly in the United States, Europe, Japan and other countries and regions.

RFID tag application

According to different energy supply methods, RFID tags are classified into active, passive and semi-active. According to different working frequencies, RFID tags are classified into low frequency (LF), high frequency (HF) and ultra high frequency (UHF). And the label of the microwave band (MW). Currently, RFID applications are mainly based on LF and HF tags; UHF tags are beginning to be scaled up, and due to their long-distance identification and low cost, they are expected to become mainstream in the next five years; MW tags have been applied in some countries. China has mastered the design technology of HF chips and successfully realized industrialization, and the UHF chip has also been developed.

RFID antenna application

At present, RFID tag antennas are mainly made of etched/stamped antennas, and their materials are generally aluminum or copper. With the development of new conductive inks, the advantages of printed antennas are becoming more and more prominent. The RFID tag package is mainly based on the low-temperature flip-chip bonding process, and new label packaging processes such as fluid self-assembly and vibration assembly have emerged. China's low-cost, high-reliability label manufacturing equipment and packaging processes are under development.

RFID reader application

There are many types of RFID readers, and some advanced products can achieve multi-protocol compatibility. China has launched a series of RFID reader products. The low-power read/write module has reached the same level in foreign countries. The high-power read-write module and the reader-on-chip system (SoC) are still in the research and development stage.

RFID application direction

In terms of application system integration and data management platforms, some international organizations have proposed RFID-based application architecture. Major software vendors have also provided RFID-enabled services and solutions in their products, and related testing and application promotion work is underway. China has achieved initial results in RFID application architecture, public service systems, middleware, system integration, and information fusion and testing. The establishment of a national RFID test center has been included in the science and technology development plan.
