What is access control? What are the common types of access control systems at present? What are the advantages and disadvantages of each?

Access control? ,? Also called access control system? Channel management system. Is it a digital intelligent management system for managers to go in and out? .

The original concept of access control system has already appeared in our lives. For example, every household in our country is equipped with doors and locks, and everyone in our own family is equipped with keys. When the family comes back, you don't have to call the door. Just use the key to open the door and go in. People outside come to visit, and people inside hear a knock at the door and know that someone is visiting. They asked, "Who is it?" The people outside replied, "I * *!" People inside judge whether to open the door by voice and past experience. This is the basic concept of access control. Wan Li Great Wall is the largest primitive access control system in ancient China.

With the deepening of social electronic intelligence, all the access control systems we see now are based on input devices? Medium? And method can be divided into:

Password access control system? ,? Card access control system? Biometric access control system

Password access control system: enter the password and the system will drive the electric lock to open the door and release it. Advantages: Just remember the password and do not need to carry other media. The lowest cost. Disadvantages: the speed is slow, and it usually takes several seconds to enter the password. If there are too many people coming in and out, you need to queue up. If the input is wrong, it needs to be re-input, which takes a long time. Poor security, it is easy for people next to you to remember other people's passwords by gestures, and passwords are easy to forget or reveal. Trend: password access control is used less and less, and it is still only used in places with low security requirements, low cost and infrequent use. For example, a safe.

Card access control system: according to the types of cards are divided into? Contact card access control system (magnetic stripe card? Bar code card) and contactless card (also called proximity card? Radio frequency card) access control system. Contact card access control system due to? Contact card is easy to wear, not often used, easy to damage, etc. And the scope of use has become less and less, and it is only used in occasions related to bank cards (magnetic stripe cards), such as VIP access control systems of banks, access control systems of unattended ATMs and other local industrial fields. Contactless IC card, due to its durability? Good cost performance? Reading fast? The advantage of high security is the mainstream of access control system at present. Therefore, at present, many people refer to the contactless IC card access control system as access control system for short.

Biometric access control system: an access control system that identifies people according to their biological characteristics. Common ones are: fingerprint access control system (everyone's fingerprint features are different), handheld access control system (everyone's metacarpal shape is different), iris access control system (everyone's retina is different through optical scanning), portrait recognition access control system (everyone's facial features and position are different) and so on. The advantages of biometric access control system are: no need to carry cards and other media, low copy probability, difficult to be copied and high security. Disadvantages: high cost. Because biometrics needs to compare many parameters and features, the comparison speed is slow, which is not conducive to crowded occasions. The biological characteristics of human body will change with the change of environment and time, so it is easy to produce rejection rate (obviously this person, but his biological characteristics have changed, not counting himself), such as fingerprints vary with seasons and humidity, palm shape and portrait change with age, and iris changes with eye diseases. Therefore, although the biometric access control system is advanced and safe, its application scope is limited, and it is only used in the fields with a small number of people, high safety requirements and high cost, and it is not the mainstream of the access control system at present.

According to different applications and objects, access control system has different derivative forms. For example: parking lot management system for vehicle access management, subway access control system for subway bus charging, etc.
