I have purchased your company’s access control device, what communication protocols should I handle when I want to do secondary development for remote door opening and card swiping?
As long as the data packet is compiled according to the door opening instruction in the protocol document and sent to the controller, the door will be opened. When swiping the card, the data report needs to be sent by the PC to start real-time monitoring instructions, and then keep the connection open, when the card is swiped, it will receive a data packet sent by the controller, which contains the controller sn, card number, and swiping time before monitoring, you need to calibrate the controller time to keep the time on both ends consistent.
