According to foreign media reports, a female hacker used an acetone solution to extract the RFID chip from Tesla’s “key card”, wrapped it in biopolymer and injected it into the left arm with a hollow needle! It’s so big, no wonder! Regarding the potential risks to human health and privacy, the author reminds us to use the technology in a more "grounded" aspect~
Radio Frequency Identification (RFID) is a technical means for non-contact two-way data communication between an electronic tag and a reader through a wireless radio frequency method to realize automatic identification and data exchange. This technology was first applied in the military field. With the development of large-scale integrated circuits, network communications, information security, and the Internet of Things, it has now entered the stage of large-scale commercial applications.
According to the statistics of RFID World Net, 78% of the items in the Internet of Things are non-smart items that cannot be self-identified. Only by using RFID technology can the connection between smart and non-smart items be realized. Before RFID was widely used, barcodes and QR codes were the main information recording and transmission tools, but RFID has the advantages of batch scanning, small size, adaptability to harsh environments, reusable, modifiable, large capacity, and penetrable. .
In particular, with the development of data processing and microelectronics technology, the cost and volume of RFID components have also been greatly reduced, and they have been widely used in many aspects such as manufacturing, logistics, food, positioning, Internet of Things, and wireless sensing. . From the perspective of the proportion of RFID applications in my country, financial payment, smart retail, and traffic management are the main application directions.
From the perspective of specific application links, in manufacturing, RFID can be used for quality control and process management in production, product life cycle management, supply chain management, logistics management, etc.; in the food industry, RFID can be used for product identification and traceability, Cold chain monitoring, shelf life warning, etc.; in addition, RFID can also be seen in scenarios such as smart medical care, smart transportation, and smart cities. It is not difficult to find that the application of RFID in all industries involves the three basic functions of identification, tracking and positioning, and information communication. According to the frequency, RFID tags can be divided into low frequency tags, high frequency tags, UHF tags and microwave tags. At present, the top three are more widely used.
Reviewing the development history of my country's RFID industry, with the joint efforts of the government, industry organizations and enterprises, through the construction of major national informatization projects (Golden Card Project), many industries have been guided to carry out RFID application pilots and accelerate market cultivation. After 2015, the market gradually Entering maturity. In 2020, my country's RFID market is expected to exceed 110 billion yuan.
According to different operating frequencies, RFID can be divided into low frequency, high frequency, ultra high frequency and microwave. In the development process of RFID, although it was the first to be widely used and promoted in the low-frequency field, the demand for high-frequency and ultra-high frequency continues to expand. At this stage, there are about 600 RFID companies in my country, which are relatively mature in the low-frequency and high-frequency fields, but there is still a lot of room for development in UHF technology.
RFID has been a technology with a relatively long commercial time. The development direction of related technologies is inseparable from the functions of RFID, that is, from being able to identify, track and locate, and communicate with information, to achieve more accurate identification, more accurate tracking and positioning, and more efficient Information communication. The potential of RFID technology is not only in the identification function, but more importantly, it promotes the intelligent development of sensors and wireless sensor networks, the Internet of Things and distributed environments. In terms of products, although low-frequency RFID has a relatively low technical threshold, new players will face greater market development risks due to the relatively narrow application market. Judging from the current product layout situation, companies that simply develop low-frequency RFID have relatively Fewer, diversified businesses have become a distinctive feature of the RFID industry. In the high-frequency RFID market, the popularization of smart cards has greatly promoted the development of the market. The tag market has not yet seen explosive growth. New players can consider the application market in special scenarios. At present, the technology for RFID is mainly in the high frequency range, but in the future development, the UHF frequency range with more powerful functions will become the mainstream direction of the RFID field, especially in the supermarket retail, aviation luggage management, Express parcels and other fields are expected to become relatively typical application scenarios, and the customized demand market will have greater market opportunities.
