Access control card reader working principle and installation method

July 13 , 2023

Access control card reader, usually called "access control reader" or "reader". As a very important part of the access control system, it is as important as the access controller. The card reader in the access control system is the most peripheral device, responsible for a series of functions such as reading card information, man-machine interface interaction, data verification and uploading.

The IC card (inductive IC card) card reader for access control is an important part of the access control system. It is the key equipment for the signal input of the access control system. If you compare an access control system to a human being, the card reader device is like the human eye. It is related to the stability of the entire access control system. If the access control system controller and electric lock are in good condition, the quality of the card reader will also cause the door to open, which will affect the acceptance and use of the decoration project. How an access control card reader works The card reader emits electromagnetic waves at a fixed frequency. The frequency is usually 13.56MHZ. When the proximity card enters the electromagnetic wave radiation range of the card reader, the coil on the proximity card reader will be triggered. Generate an electric current and trigger the antenna on the proximity card, send a signal with the card information to the card reader, the card reader converts the liquid level signal into a digital serial number, sends it to the local controller, and the local controller uploads the information . Finally, the superior controller is uploaded to the access control server, and the access control server compares the card number with the information in the database to obtain all card information.


The installation method of the access control card reader first selects the installation location, and the metal that stops on the metal has a shielding effect. If the card reader is installed on the metal, it will emit radio waves and be blocked by the metal. The installation environment of the card reader must be accepted during the installation process. For example, when installing a card reader, a plastic plate should be installed over the metal plate on the back of the card reader. Secondly, the distance between the two card readers should not be less than 30/cm. When the distance between the two card readers is too close, the two card readers will emit radio waves at the same time, so that the radio waves interfere with each other. The card is slower, and if you are too close, the card will not be read. If conditions do not permit, a shield can be added on one of the readers. Install Surge Shielding Start all data lines and reader wires to install surge shielding. While it's unlikely you'll be setting your device up directly from a lightning strike, as part of your downside system, you should know that a surge protector is one piece of equipment that isn't missing in the lightning protection deployment of electronic equipment. Surge protectors will protect against similar lightning strikes and deploy equipment in a closed state in special environments. All wires are used in the housing, PVC pipe and galvanized pipe can be used to prevent the signal from drying out and the mouse from biting the line. Especially when it is necessary to use strong electricity, it must be carefully connected to the case.
