As the name suggests, the access control system is a system for controlling the entrance and exit passages. It is developed on the basis of traditional door locks. Common access control systems include: password identification access control system, card recognition access control system, biometric access control system, etc.
Password identification access control system
Access authority is identified by checking whether the password entered is correct. These products are further divided into two categories, one is the common type, and the other is the random keyboard type (numbers on the keyboard are not fixed and change automatically from time to time). The advantage of password identification is that it is easy to operate, no need to carry a card, and the cost is low. The disadvantage is that the safety is poor and it is easy to leak, it can only be controlled in one direction, there is no record of opening the door, and the buttons are easy to be damaged and malfunction.
Swipe card identification 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 contactless card (also called induction card, radio frequency card) access control system. Contact products are easy to wear and tear, easy to copy information, and easy to be invalidated by external magnetic field interference for contact products. There are few usage scenarios, and they are generally only used in occasions related to bank cards (magnetic stripe cards). Contactless cards have the advantages of convenient use, strong durability, fast reading speed, and high security.
Biometric Access Control System
Identification of entry and exit by means of inspection of personnel's biometrics. There are fingerprint type, palm type, iris type, facial recognition type, finger vein type and so on. Its advantages are that it will not be lost, will not be stolen, has no burden of remembering passwords, and is safe and convenient. However, at present, the stability and accuracy of biometric identification are still being further improved, and the product price is also higher than the previous two types, and the applicable scenarios also have certain limitations.
