  • Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Jul 17 '23 at 16:10
  • i have installed my software at location "A", my device at location "B" and database at location "C", my device and software is connected on the same network vis tcp/ip, my software receives data from my device and stores it to my db. if my software is shutdown for some reason, my device will let them scan and open the door can you explain how will i be able to store the check in or check out info of that user when the system is turned on? cant find anything in the SDK – ABJ4727 Jul 19 '23 at 12:18
  • @ABJ4727 you're doing it wrong. The fingerprint device is just a sensor or a reader. It does not track check-ins & check-outs, not does it open nor close the door. You need to connect to the main controller. See this: https://github.com/MuaazH/ZKTeco_PULLSDK_Wrapper/ – MuaazH Aug 07 '23 at 13:15
