The role 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.
