Overview of Access Control Card Reader
Access control card reader generally referred to as "access control reader" or "reading head". As a very important part of the access control system, its importance is no less than that of the access control controller. The non-contact IC card (inductive IC card) reader for door prohibition is an important part of the access control system and a key device for the signal input of the access control system.
If you compare the access control system to a person, the card reader is like a person’s eyes. It is related to the stability of the entire access control system. If an access control system controller and electric lock are good, but the quality of the card reader is defective, it will also cause the door not to be opened, which will affect the acceptance and use of the project. Therefore, because the price of the card reader is relatively small compared to the access control system, it is not enough to pay attention to the selection of the card reader, and there is a certain degree of arbitrariness.
Access control card reader features
The card reader in the access control system is the most peripheral device, which is responsible for a series of functions such as reading card information, man-machine interface interaction, data verification, and uploading. Its importance is self-evident, so the card reader needs to have the following characteristics.
1. Security: Security is the foundation of the card reader, including the security of the card reading method, the security of the communication method, the anti-violence design, the dustproof and waterproof design, the tamper-proof design, the design of the tamper-proof mechanism, etc.
2. Stability: The stability of the smart card reader refers to the ability of the card reader to work stably. The stability of the card reader will be an indispensable part of the system stability, including wide temperature design; electromagnetic compatibility; lightning protection, etc.
3. Beautiful appearance and harmonious environment: The development trend of card readers shows that the concept of specially designing card readers according to different use environments has gradually entered the hearts of the people. Different applications, different users, different architectural styles, and other complex requirements have introduced more detailed industrial design to the reader. The reader is no longer just abruptly as the vanguard in the all-in-one card system but has become the entire application The natural and harmonious part of the scene.
4. Human-machine interface friendliness: With the continuous development of card reader technology, the functions it provides are from simply reading the card number and uploading it to the controller, but adding more friendly features and providing colorful humanity Modification function and operation mode.
5. Economical and convenient installation and debugging: In addition to providing users with safe, stable use and beautiful and harmonious appearance, the success of the card reader is largely reflected in the economy and convenience of installation and debugging. . For example: pay attention to the location of the installation holes, the use of full connector design, the economy and flexibility of wiring, the input/output port design, and so on.
6. Energy saving and environmental protection: Energy saving and environmental protection will be an important trend in the development of card readers in the future, including low-power design and electromagnetic radiation for reducing energy consumption. Low-power design needs to start with both software and hardware, such as power supply voltage, microcontroller structure, system clock design, and low-power mode.
