When it comes to the Internet of Things, many people are familiar with it, abbreviated as the Internet of Things. In the initial conception,
RFID was seen as the foundation of the Internet of Things. As long as
RFID tags are attached to each item, recording its relevant information, the item information can be read out through
RFID, and a fast identification network system for items covering the whole world can be established. So what is the relationship between
RFID and the Internet of Things? Firstly, we need to understand what the Internet of Things is.
What is the Internet of Things?
The Internet of Things is a concept with extremely broad connotation. It does not refer to a particular technology, but refers to a network based on the Internet, traditional telecommunications networks and other information carriers, enabling all ordinary physical objects that can be independently addressed to achieve interconnection and interoperability. It can connect various terminal devices, industrial systems, building control systems, home intelligent facilities, video surveillance systems, etc. to the Internet of Things domain name through various wireless and/or wired long-distance and/or short distance communication networks for interconnection.
In a word, the Internet of Things is to connect all items with the Internet through information sensing devices for information exchange to achieve intelligent identification and management.
What is the relationship between
RFID and the Internet of Things?
The development of the Internet of Things to its current level does not specifically refer to a single technology, but rather a collection of various technologies. Currently, the Internet of Things mainly relies on three technologies:
RFID (Radio Frequency Identification), sensor technology, and embedded system technology.
The origin of
RFID technology dates back to 1948. In the 1970s,
RFID technology was still in its early exploratory stage until the 1980s and 1990s, when
RFID technology and products entered the commercial application stage and various scale applications began to emerge. After entering the 21st century,
RFID products have been widely adopted, and standardization issues have become increasingly important. The types of
RFID products have become more diverse, and active, passive, and semi passive electronic tags have all been developed. The cost of electronic tags continues to decrease, and the scale of application industries has expanded.
At present,
RFID technology is widely used in civilian fields such as production automation, access control, highway toll collection, parking lot management, identity recognition, and cargo tracking. Its new application scope is constantly expanding and emerging.
Advantages and disadvantages of
RFID technology
Compared with traditional barcode technology, it is inferior to radio frequency identification technology in terms of updating data, storing information, service life, work efficiency, and security. It cannot adapt well to the current social development needs in China and is also difficult to meet the needs of industries and related fields.
Radio frequency identification technology can be widely applied to multiple industries and fields precisely because it has advantages in real-time updating of data, storage of information, service life, work efficiency, security, and other aspects. The service life of
RFID tags is long. As long as the staff pays attention to protection during use, they can be reused. Radio frequency identification technology has changed the inconvenience of information processing in the past, achieving simultaneous identification of multiple targets and greatly improving work efficiency.
However,
RFID technology also has certain shortcomings.
RFID electronic tags are relatively expensive compared to ordinary barcode tags, so most of the companies currently equipped with
RFID systems are financially strong. There is also a lack of uniformity in various standards. Countries such as the United States, Japan, and China have different standards, and in order to meet the usage needs of different countries, it is necessary to adapt to different agreements.
In fact, the relationship between
RFID and the Internet of Things is not difficult to understand.
RFID technology is one of the fundamental technologies for realizing the Internet of Things and is the basis for realizing the information infrastructure of the Internet of Things. With the rapid development and widespread application of
RFID sensing technology, it is believed that
RFID will also have a more profound impact in multiple fields
