The Role of RFID Security Door

How to choose one of the many smart library devices to form the simplest library management system? The answer is the RFID security door. All books with RFID electronic tags cannot be modified to prevent theft. All readers can only read within the specified range and cannot be taken away from the site. This naturally achieves the purpose of book management.
 

The rfid security door is an RFID anti-theft device installed at the entrance and exit to detect whether the electronic tag meets the conditions for taking out. Realize rapid detection of electronic tags in three-dimensional space within the sensing range of the antenna. When an illegal tag is detected, an audible and visual alarm can be triggered. It can be used in libraries, archives, import and export anti-theft, brand clothing store anti-theft and other fields. The main function of the RFID security door is to prevent theft, followed by counting the flow of people entering and exiting through infrared; for some special needs, the status of the RFID security door will be displayed in the form of lights. For example, if the equipment status is abnormal, a yellow flashing light will appear. Below is a green or blue ambient light that flashes red when the alarm is triggered. There are also people flow data displays that are integrated into a screen. Compared with the people flow numbers displayed in the control center, the display with a screen is simpler. The anti-theft detection methods of security doors are divided into three types: AFI, EAS, EAS and AFI. Because RFID electronic tags can repeatedly modify information and status, compared with magnetic induction security doors, they can detect the tag status more accurately and reduce the loss rate of items.
 

The information of the item is stored in the RFID electronic tag, which requires specific equipment to be modified and can be modified repeatedly. It has more advantages than barcodes for anti-theft. As long as the tag is within the sensing range of the RFID security door antenna, the tag information and status can be accurately read. Even if multiple tags overlap or are wrapped with non-metallic substances, they can be identified and read, and support multi-channel use side by side.
