After Years of Development, the Types of Access Control Systems Are Gradually Diversified_ Taigewang

After years of development, the type of access control system has also changed from single to diversified. As the name suggests, access control system is a system used to adjust and control the access of the gate. It is developed on the basis of traditional door locks. Common access control systems include password identification access control system, card identification access control system, biometric access control system, etc. Password identification the access control system identifies access rights by verifying whether the entered password is correct. It is divided into two types, one is the common type, the other is the disordered keyboard type. The advantage of password recognition is simple operation, no card and low cost. The disadvantages are poor safety, easy leakage, only one-way control, no door opening record, easy damage of keys and failure. Card swiping identification access control system can be divided into contact card access control system and non-contact card access control system according to the type of card. Contact products are easy to wear due to contact, cards are easy to copy, are easy to be damaged by external magnetic field, and the use scene is small. Generally, it is only used for bank cards and other occasions. Non-contact cards have the advantages of convenient use, strong durability, fast reading speed and high security. Biometric access control system identifies access by checking people's biometrics. There are fingerprint type, palm type, iris type, face recognition type, finger vein type, etc. Its advantage is that it will not be lost, stolen, safe and convenient. However, the stability and accuracy of biometrics are still further improved, and the product price is also higher than the first two categories. The applicable scheme also has certain limitations.
