At the early stage when RFID just entered China market, the development was mainly guided by the government that most RFID projects were closed-loop and led by the country, and most of which were HF (high frequency) 13.56 MHz. As a result, after many years’ development, Chinese RFID manufacturers are highly competitive in HF (high frequency) chip design and production, HF ticket manufacturering, and encapsulation technology.
However, in recent years, with the rapid economic development, the demand of various industries to use informative technology to improve efficiency is larger and larger. UHF (ultra high frequency) RFID has begun to enter all industries and become the mainstream of future development. In general, the development of RFID technology presents the following trends.
Higher encryption capabilities
With the rapid development of RFID technology and the continuous decreasing of the production cost of RFID tags, the application of RFID tag’s anti-counterfeiting technology has also been greatly popularized, highlighting the demand in the fields of transportation, ticketing security, and product anti-counterfeiting.
Compared with other anti-counterfeiting technologies, the advantage of RFID is that each tag has a globally unique identifier (UID), and it also has storage space with encryption function, which can carry more encrypted information or store data related to actual applications. No matter from the perspective of security or application flexibility, the anti-counterfeiting technology of RFID tag has unparalleled advantages.
System developing towards integration and miniaturization
As RFID technology has been applied in more and more industries, RFID has started to integrate with printing, papermaking, and packaging technologies, which has further enriched the types of products and has more and more application scenarios.
As the application of RFID systems continues to mature, the development trend of RFID reader design and manufacturing is multi-function, multi-interface, multi-standard, and to modularization, miniaturization, portable, and embedded. At the same time, multi-reader coordination and networking technology will become one of the future development trends.
Integrated with sensor
In recent years, more and more manufacturers have started to combine RFID technology with sensor technology. The new RFID sensor tag incorporates the sensing capability into the original functional characteristics of the RFID tag, which greatly improves the tag’s function and application flexibility.
At present, the most widely used RFID sensor tags are RFID temperature sensor tags, such as RFID sensor tags for monitoring tire temperature and pressure, RFID tags for real-time monitoring and management of blood quality, and RFID tags for temperature monitoring and traceability of medical cold chain logistics, etc. In addition, it also has applications in warehousing and logistics, electricity, medical care, automobiles, agriculture and other fields. With the increasing of related exploration, RFID technology will be developed for more and more fields with more functions.
