What is an access control system? The original concept of access control system has actually been in our life for a long time. For example, every house in our house is equipped with doors and locks, and the family members directly use the key to open the door when they go home. Judging whether to open the door by sound and past experience.
Access control system, also known as access management control system and channel management system, is a new type of modern intelligent management system. It is an effective measure to solve the security management of the entrance and exit of important departments. Applicable to various scenarios, such as banks, hotels, parking lot management, computer rooms, prisons, express cabinets, offices, intelligent communities, factories, etc.
With the deepening of social electronic intelligence, the access control systems we see now can be divided into: password access control system, card swiping access control system, biometric access control system, and mobile phone APP access control system according to different input device media and methods.
Password access control system: By entering the password, the system judges that the password is correct and then opens the door. Advantages: Just remember the password, which is simple. Disadvantages: slow speed and poor security. Trend: There are fewer and fewer occasions for password access control. It is used in occasions with low safety requirements, low cost, and infrequent use. Example: safe.
Swipe card access control system: According to the type of card, it is divided into contact card access control system (magnetic stripe card barcode card chip card) and contactless card (also called proximity card radio frequency card) access control system. The contact card access control system is mainly used in bank card-related Occasionally, non-contact IC cards are widely used due to their advantages of high durability, good cost performance, and fast reading speed, but the disadvantage is that they are easy to be copied. (Remarks: Ordinary IC/ID cards are easy to be copied, and CPU cards are also called encryption cards, which are not easy to be copied, but the cost is higher)
Biometric access control system: An access control system that identifies identities based on different human biological characteristics. Mainly include: fingerprint access control system, palm type instrument access control system, iris access control system, face recognition access control system. Advantages: no need to carry cards and other media, less chance of duplication, not easy to be copied, high security, disadvantages: high cost. The comparison speed is slow, which is not conducive to occasions with too many people. The biological characteristics of the human body will change with the environment and time, and the recognition rate is low. Although the biometric access control system is advanced and safe, the scope of application is limited, and it is only applied in a few fields such as a small number of people, high security requirements, and high cost.
Smart phone access control system: Remotely open the door by installing the mobile phone APP. At present, there are mainly the following ways to open the door by mobile phone: mobile phone QR code to open the door, smart phone APP to open the door, mobile phone NFC to open the door, mobile phone Bluetooth to open the door, and mobile phone Wechat applet to open the door. Mobile phones are playing an increasingly important role in our lives. Due to their convenience, low cost, fast reading speed, and high security, they are bound to become the mainstream of access control systems in the future.
The access control system also has some derivative forms according to its application occasions and application objects. For example: parking lot management system for vehicle entry and exit management, subway access control system for subway bus charges, etc.
