The Internet of Things is an extremely broad concept and does not specifically refer to a certain technology, while RFID is a well-defined and fairly mature technology.
Even when we mention the Internet of Things technology, we must clearly see that the Internet of Things technology is by no means a specific technology, but a
collection of various technologies, including RFID technology, sensor technology, embedded system technology, and so on.

1.The early Internet of Things took RFID as the core

Today, we can easily feel the strong vitality of the Internet of Things, and its meaning is constantly changing with the development of the times, becoming more abundant,
more specific, and closer to our daily lives. When we look back at the history of the Internet, the early Internet of Things has a very close relationship with RFID, and it can
even be said that it is based on RFID technology. In 1999, the Massachusetts Institute of Technology established the “Auto-ID Center (Auto-ID). At this time, the awareness
of the Internet of Things is mainly to break the link between things, and the core is to build a global logistics system based on the RFID system. At the same time, RFID
technology is also considered to be one of the ten important technologies that will change the 21st century.

When the entire society entered the Internet age, the rapid development of globalization transformed the entire world. Therefore, when the Internet of Things is proposed,
people have consciously set out from the perspective of globalization, which makes the Internet of Things stand at a very high starting point from the very beginning.

At present, RFID technology has been widely used in scenarios such as automatic identification and item logistics management, and it is one of the most important ways to
identify items in the Internet of Things terminal. Due to the flexible data collection capabilities of RFID technology, the digital transformation work of all walks of life is
carried out more smoothly.

2.The rapid development of the Internet of Things brings greater commercial value to RFID

After entering the 21st century, RFID technology has gradually matured and has subsequently highlighted its huge commercial value. In this process, the price of tags has also
fallen along with the maturity of technology, and the conditions for large-scale RFID applications have become more mature. Both active electronic tags, passive electronic tags,
or semi-passive electronic tags have all been developed.

With the rapid economic development, China has become the largest producer of RFID label products, and a large number of R&D and manufacturing companies have emerged,
which has given birth to the development of industry applications and the entire ecosystem, and has established a complete industrial chain ecology. In December 2005,
the Ministry of Information Industry of China announced the establishment of a national standard working group for electronic tags, responsible for drafting and formulating
national standards for China’s RFID technology.

At present, the application of RFID technology has entered all walks of life. The most typical scenarios include shoe and clothing retail, warehousing and logistics, aviation, books,
electric transportation and so on. Different industries have put forward different requirements for RFID product performance and product form. Therefore, various product forms
such as flexible anti-metal tags, sensor tags, and micro tags have emerged.

The RFID market can be roughly divided into generalized market and customized market. The former is mainly used in the fields of shoes and clothing, retail, logistics, aviation,
and books with a large amount of tags, while the latter is mainly used in some areas that require more stringent label performance. , Typical examples are medical equipment,
power monitoring, track monitoring and so on.With the increasing number of Internet of Things projects, the application of RFID has become more and more extensive. However,
the Internet of Things is more of a customized market. Therefore, in the case of fierce competition in the general-purpose market, customized solutions are also a good
development direction in the UHF RFID field.
