There is a LED indicator light on the cover of the box. When the valid card is swiped, there will be a green arrow to indicate the direction of passing; 6. Can be used in the same system with other styles of access gates. 7. It has the function of fault self-check and alarm prompt, which greatly facilitates maintenance and use. 8. It has a unified and standard external electrical interface, which can be connected with other reading and writing devices for easy integration, and remote control and management can be achieved through a management computer. 9.
