Coal Gangue To Make Environmentally Stone Paper Goods

With the rapid development of science and technology, the security technology is also constantly upgraded. The application of RFID technology in the access control system not only promotes the technical innovation of the access control system, but also promotes the open development of the access control system. RFID electronic tag card, RFID card is cheap, easy to use, high security and can be well managed with a database, its cost performance is very high, and it has a good prospect for promotion.

The rapid development of RFID technology, the diversification of RFID products in various frequency bands, and radio frequency identification technology have been recognized by RFID manufacturers and continue to reduce costs, driving various RFID products into our daily lives.

Different RFID electronic tags can be used in different occasions, which can realize multi-target recognition, moving target recognition and remote real-time monitoring and management. The communication distance can be from a few centimeters to tens of meters. Its main advantage is that it has strong environmental adaptability and is less affected by rain, snow, hail, and dust. It can work around the clock and complete automatic identification, tracking, and management without contact. It can penetrate non-metallic objects for identification, and has strong anti-interference ability.

RFID access control systems have long gone beyond traditional doorway and key management functions. The safety requirements of modern working environments, departmental administrative management work, daily attendance management, and company catering consumption are all closely related to the access control system. Installing RFID access control systems in some office places, residential apartments, and other public entrance and exit channels can effectively prevent unauthorized people from entering and maximize the security of these places.

The RFID open access control system not only has all the functions and features of a traditional ordinary access control system, but also has the characteristics of an open multi-person fast passage and simultaneous recording of the personal information of each person in and out.

When a person wearing a radio frequency ID card passes through the gate, the information in the ID card is automatically collected by the system without manual intervention, making access control management more convenient. The electronic tag card has a long service life, can be read and written more than 100,000 times, and the service life is up to more than ten years.

Automation, informatization, and intelligence have become the needs of the development of the times. Infinite technology and computer technology have also continued to develop. The Internet of Things industry is becoming more and more widely used. The RFID access control system is a good reflection of the practicality of the Internet of Things. The RFID access control system has high security and reliability, and is easy to use.
