I bought your company access control devices. What kind of communication protocol do I need to deal with when I want to open a remote door and swipe card?

Just compile the packet according to the  protocol document  and send it to the controller and the door will be opened.

The data report needs to be sent the start real-time monitoring instructions

by PC when swiping the cards. Then keep the connection open. When swiping the cards, the data packet sent by the controller will be received, including the controller sn, the card number, the time of swiping cards.

Before monitoring, it is necessary to calibrate the controller time to keep the two ends consistent.
