The role and technical type of Metal RFID Card Reader

The Metal RFID Card Reader is a device for reading data from a card. It is an access control component that directly contacts the user. Its function is to read and identify the identity information of the entrant. Typically, identity information can be card number, personal password, fingerprint or other important information used to identify and prove an individual's identity.


Metal RFID Card Reader is an important part of the access control system. It is the key equipment for the signal input of the access control system. It is related to the stability of the entire access control system. If an access control system controller and electric lock are good, if the quality of the card reader is problematic, it will also cause the door to open, which will affect the acceptance and use of the project.

Metal RFID Card Reader technology type

1. According to the radio frequency division:
Low frequency 125KHz: Using radio wavelength 125KHz, standard proximity technology, has been gradually replaced by high frequency technology as a relatively old standard.
High frequency 13.56MHz: The radio wavelength is 13.56MHz, which allows reading, writing and encryption to improve security. Due to the higher communication speed, it is more suitable for biometric identification and processing special security and anti-counterfeiting certification. High-frequency technology has become the mainstream development trend in the current market.


2. According to the iOS standard of high frequency technology:
ISO14443: International standard non-contact technology, usually reading distances up to 10 cm. The advantage is that the processing speed is fast, and it is suitable for information transmission with a large amount of data, such as biometric technology.
ISO15693: International standard non-contact technology, VICINITY technology, usually reading distance greater than 10 cm. Its advantages are longer read range and lower power consumption.
The standardization of the access control system makes the Metal RFID Card Reader more and more popular as an access control card reader.

Metal RFID Card Reader is an important part of the access control system. It is the key equipment for the signal input of the access control system. If the access control system is compared to one person, the Metal RFID Card Reader is like a human eye. It is related to the stability of the entire access control system. If an access control system controller and electric lock are good, if the quality of the card reader is problematic, it will also cause the door to open, which will affect the acceptance and use of the project.

Analysis of Access Control Board TCP/IP Communication Mode

图片
Access Control Board networking solution realizes communication automation, office automation and management automation. It is based on integrated wiring system and uses computer network as a bridge to realize comprehensive management of communication system and office automation system. TCP/IP communication protocol is the current computer network universal standard protocol, which has the advantages of fast transmission speed, international standard and good compatibility. The access mode of the controller is the same as that of the HUB of the local area network and the computer network card. 1. Communication distance: In a small local area network, the communication distance can be extended by the cascade of HUB. The communication distance of each level is up to 100 meters, and multiple levels can be cascaded. Moreover, in large-scale local area networks, it can be extended to a long distance or even a few kilometers through various methods such as fiber-optic wireless, and ev

Access Control System and NFC Technology Realize the Development of Mobile Access Control

图片
With the development of NFC, the access control system extends the wireless access control device based on this technology, which has no complicated wiring and no noisy wall piercing. This also adds new vitality to the access control system category, and integrates into the ranks of the access control system, adding a beautiful landscape to the convenient office. The mobile access control of NFC technology is constantly upgraded, which will lead the access control system to a safer development stage. So what is the access control of NFC technology? If you talk about the NFC function of your mobile phone, I believe that everyone is no stranger. It is implemented by NFC technology, also known as short-range communication, which is a communication protocol that allows two electronic devices to communicate at a distance of a few centimeters. Combined with this technology, mobile access control, it can combine the door lock with the access control machine, simplify the redundant part
