Access control system classification


Password identification access control system


Identify the access authority by verifying whether the entered password is correct. This type of product is divided into two categories, one is the ordinary type, and the other is the out-of-order keyboard type (the numbers on the keyboard are not fixed and change automatically from time to time). The advantage of password recognition is easy operation, no need to carry a card, and low cost. The disadvantage is that the security is poor and easy to leak, it can only be controlled in one direction, there is no record of opening the door, and the keys are easily damaged and malfunction.


Swipe to identify the access control system


According to the type of card, it can be divided into contact card access control system (magnetic stripe card, barcode card) and non-contact card (also called proximity card, radio frequency card) access control system. The cards used for contact products are easy to wear due to contact, information is easy to copy, and it is easy to be invalidated by external magnetic field interference. There are few usage scenarios, and they are generally only used in occasions related to bank cards (magnetic stripe cards). Non-contact cards have the advantages of convenient use, strong durability, fast reading speed, and high security.


Biometric Access Control System


Identify entry and exit by checking the biometrics of personnel. There are fingerprint type, palm type, iris type, facial recognition type, finger vein type and so on. Its advantages are no loss, no theft, no burden of remembering passwords, safety and convenience. However, the stability and accuracy of biometric identification are still being further improved, and the price of products is higher than the previous two categories, and the applicable scenarios also have certain limitations.


New access control system


In recent years, new forms of access control systems such as QR codes, Bluetooth, and WIFI have emerged. Residents can use the mobile app to open the door near the access control machine after verifying their identity through the mobile phone APP. At the same time, the residents can also generate a QR code image that authorizes the visitor to open the door and share it with the visitor. The visitor's QR code has a time limit and the number of times to open the door.
