As an important technology in the access control industry in the security field, identification has not only been applied to access control systems. Today, people's increasing demand for life safety, identification technology has gradually penetrated into many aspects of people's lives. According to industry predictions, the RFID technology market as a branch of identification technology will bring $ 3 to 10 billion in business opportunities in new products and services in the next five years, including servers, data storage systems, database programs, and business management. There is a huge demand for software, consulting services, and other computer infrastructure. It can be said that identification technology is no longer a field of pure security. The industrial chain derived from it will achieve the reintegration of resources in various industries. This is far more significant for security itself than it brings to the access control system. Profit and business opportunities.
Understand the concept of recognition technology
Radio frequency identification systems are usually composed of electronic tags (radio frequency tags) and readers. There is a certain format of electronic data in the electronic tag memory, which is often used as identification information of the item to be identified. In application, the electronic tag is attached to the item to be identified as an electronic mark of the item to be identified. The reader and the electronic tag can exchange information according to the agreed communication protocol. Usually, the reader sends a command to the electronic tag. According to the received command of the reader, the electronic tag returns the identification data of the memory to the reader. . This communication is achieved in a non-contact manner, using the spatial coupling of alternating magnetic or electromagnetic fields and radio frequency signal modulation and demodulation technology.
Biometric technology mainly refers to a technology for identity authentication through human biometrics. Biometrics here usually have unique (different from others), can be measured or can be automatically identified and verified, unchanged for life and so on. The core of so-called biometrics lies in how to obtain these biometrics, convert them into digital information, store them in a computer, and use reliable matching algorithms to complete the process of verifying and identifying personal identities.
Market prospects brought by the application of identification technology
In recent years, the recognition industry has successfully transitioned from the initial stage of steady development to the mature stage of rapid development. Regardless of whether it is the establishment of a market system or technology research and development, recognition technology is no longer limited to the field of security. At the same time, based on the benign development environment of the domestic security market, this field has gradually entered the stage of comprehensive application from the exploration stage, and has also brought unlimited development opportunities for domestic identification technology security companies.
Because the RF card can be made relatively small and exquisite, it can be placed on the item without being noticed, as the protection of valuable items can play a very good role, so it has been successfully applied to various fields, such as mobile payment, logistics systems, food Source tracing, and electronic anti-theft of major retailers and so on. At the same time, due to the real-time nature of RFID technology, it can add other functions to achieve a wider range of uses, such as adding environmental monitoring sensors to the RF card, then when transporting some items with high environmental requirements-such as drugs, it Real-time monitoring technology can be used to avoid environmental impacts during transportation.
Although biometrics is not widely used in radio frequency identification, it is still mainly used as an extension of access control identification technology to achieve the purpose of increasing security through the biological characteristics of the organism itself. However, the introduction of biometric standards can be said to be inestimable for this research field. China's relevant standardization agencies also attach importance to its development. The national standard of "Information Security Technology Iris Recognition System Technical Requirements" (GB / T20979-2007) was reviewed and approved by the National Standardization Management Committee and was officially implemented on November 1, 2007. This is the first national standard in the field of biometric identification in China.
Identify problems in the process of technological development
Any new technology must be tested before it can be retained and promoted. Despite the steady pace of recognition technology, there are still many stumbling blocks that need to be kicked off on this road, and these stumbling blocks are not a bad thing. It is the continuous improvement of this technology by defeating them.
For RFID technology, the biggest problem is the production cost. Although RF cards have been used in many fields, they are still mainly based on high-cost products. For most retail industries, the large-scale replacement of barcodes by RFID is not a short-term thing, especially for second- and third-tier cities. In terms of comprehensive replacement, it will take time. Secondly, for high-secrecy units or areas that require comprehensive monitoring and real-time tracking of people ’s whereabouts, RFID technology is slightly inadequate, and other systems are needed to assist, and only using other mature systems can meet security needs. Standby or second protection. Therefore, RFID is not mature in terms of personnel protection.
Let's look at biometrics technology, mainly two technical issues. First, both the low rejection rate and high accuracy cannot be well guaranteed at the same time. Second, the recognition rate is slow. Domestic recognition technologies, especially the more sophisticated technologies such as human face, veins, and retina, cannot achieve the unity of high speed and low price in recognition speed.
The future development of identification technology
In my opinion, both RFID technology and biometric technology have inestimable development prospects. In comparison, the application and promotion of RFID technology will be even better. The application of smart cards based on the principle of RFID meets people's needs for information and electronic life and is more convenient to use. At the same time, the research and development and application of a combination of multiple functions also make the smart card more powerful, so future applications will become mainstream.
Although there are few supporting facilities for biometrics, the requirements for technology are higher. Although large-scale applications are slightly inferior to radio frequency identification technology, the room for future technological improvement will be greater.
The definition of electric strapper: electric strapper is to be packaged with electric tension, friction buckle, automatic banding with a strapping a strapping machinery.
It mainly consists of five parts: 1, the motor part; 2, the electric part of the tightening; 3, the deduction to do part of the friction; 4, the body;
Electric strapper works: the plastic band or plastic packing belt, wrapped around the object from the top after a lap, the packing with the joints into the machine working tank, driven by the motor tightening wheel, the packing belt tight , By friction as a way to buckle with adhesive, and finally automatically cut.
Electric strapper features: high flexibility, fast, safe, easy and environmentally friendly.
