Highly intelligent: Through computer software, you can complete highly complex management functions. For example, you can use a master control card to open all the door locks, use a cleaning card to unregister all the cards of the door lock, and use the clock card to open the door for a limited time. In addition, because the lock has a large amount of door opening information stored, it can be easily queried and counted. Information can also be provided to help solve the case after the theft. Convenience: Since you can use one card for multiple purposes (for example, the same card can open multiple doors and safes) and "one card" (for example, the same card can also be consumed), you can avoid carrying a lot of keys and cash. Reliable: IC card door locks generally use electromechanical dual control, that is, in addition to the IC card can be opened, and a mechanical key for backup (mechanical key opening also has a record). According to the way of reading and writing the IC card, it can be divided into: Inductive: Easy to use, less durable due to mechanical wear, low failure rate, and IC card can produce different shapes (such as the shape of a traditional key), but the price is high. According to the connection method of the IC card door lock, it can be divided into: Networking type: Each IC card door lock is connected to the computer through the RS485 network, so that the main control computer and the door lock can communicate in real time to achieve real-time monitoring (such as monitoring the door open state and alarming when opening the door illegally). When the system fails in the communication system (computer or network cable), the door lock can work independently. After the communication is resumed, the information after the off-network is automatically uploaded. The disadvantage of this system is that the wiring is complicated and the engineering quantity is large, and it is generally applied to the access control system. Separate type: Each IC card lock works independently, and the information stored in it passes through the data card to the computer. The system is widely used in hotels without wiring. Family type: It is a special type of individual type. It uses the door lock to issue cards, which saves the computer and card issuing machine and can be applied to home and small writing rooms.

IC card door lock on the mechanical lock plus the IC card read and write circuit, using the IC card complex password verification and identity authentication, send an unlock signal to the control circuit, and then trigger the motor (or magnetic switch), linkage lock tongue, Thereby completing the door opening function.
