What is the application of RFID technology in the RFID channel access control system

1. The access control swipe system usually uses radio frequency identification (RFID) Technology, which belongs to the perception layer technology.Specifically, a reader and an access control card with a chip will be installed in the access control card system.

2. Use it with RFID gate machine or self-service check-in box. Compared with ordinary access control, guests only need to wear an RFID badge to walk through it to achieve non-stop check-in. Through the identification of card reader equipment, they can realize check-in and information display, and the style is also more beautiful.

3. Passage mode: support swipe to open the door, multi-card door opening, first card to open the door, password to open the door, swipe + password and other door opening methods; frequent opening, frequent closure and other access methods. 4) Precise permission control: Accurately control the permission and access method of any person to any door at any time.

4. Access control system: High-frequency RFID technology can be used in the access control system to realize automatic identification and access control of personnel, and improve safety and convenience.Payment field: High-frequency RFID technology can be used in mobile payment and NFC payment to achieve a fast and convenient payment experience.

5. A powerful intelligent network access control system composed of management system, controller, induction card reader, electronic lock, etc. Personnel holding a legal induction SM1 card can automatically control the electronic lock allowed to be opened through the SM1 card reading device.

What modules are mainly included in the hardware part of the RFID access control system? What are the functions of each module? _Baidu...

The reader can be a reading or reading/writing device depending on the structure and technology used. It is the information control and processing center of the RFID system. Readers are usually composed of coupling modules, sending and receiving modules, control modules and interface units.

RFID system consists of three parts: label, reader and antenna. Label: Labels are divided into two types: active and passive. The active label has a built-in battery, which can actively send signals;Passive tags, on the other hand, rely on the antenna to receive energy from the reader and use this energy to feedback the required signals.

The software components in the RFID system mainly complete the storage and management of data information and the read and write control of RFID tags, which are independent of the RFID hardware. RFID systems are ultimately for application services, and the interface between the reader and the application system is usually completed by software components.

RFID inventory machine: When you need to take stock of fixed assets, you need to use RFID inventory machine to take stock of the assets of the enterprise. After the inventory, the data information is instantly transferred to the fixed asset management system and converted into inventory points and inventory balance tables.

What kind of perception layer technology is used for access control swipe?

1. Radiofrequency identification (RFID): This is a non-contact technology that connects items with electronic tags through radio signals, which can be used to track and manage items. RFID technology is often used in logistics and supply chain management.

2. The information in it can not only be read, but also written and modified, so the chip card is not only a key, but also an electronic ID card. Because as long as you write your personal data in the chip, you can know who is in and out in the card reader. The same technology is also used for anti-theft chips and so on in shopping malls.

3. The access control card is RFID technology. Radio frequency label is the physical carrier of product electronic code (EPC), which is attached to traceable items and can be circulated around the world, identified and read and written.RFID (Radio Frequency Identification) technology, as a key technology to build the "Internet of Things", has attracted attention in recent years.

What are the advantages of RFID access control system compared with ordinary access control?

1. Card identification is divided into 2 categories: the first is to use a magnetic card, but the magnetic card has low security, is easy to wear and needs to be magnetized frequently; the second is an RFID card. RFID card is cheap, easy to use, highly secure and can be managed well with a database, which is extremely cost-effective. High, with good prospects for promotion.

2. Advantages: Excellent security from the perspective of recognition;No need to carry a card. Disadvantages: the cost is very high.

3. RFID technology can achieve the advantages of non-contact, high efficiency, low cost, etc., and is widely used in logistics, warehouse management, production and manufacturing and other fields. In the access control card system, it can also provide a convenient, fast, relatively safe and reliable way of identity authentication.

4. It is more convenient and safer than ordinary mechanical locks. High security adopts advanced international internal encryption protocols, and outsiders cannot open your electric lock to enter your premises by mechanical or other high-tech methods. The remote-controlled door opening function is specially added to the remote-controlled door opening function. You can open the door with a light press within a range of 100 meters without getting up.

5, lgp=A+B/T. In the formula: P - vapor pressure on the surface of the liquid, T - boiling point (absolute temperature), A, B - constant.
