title: ZKTeco Push SDK
body: <p>i'm new to ZKteco devices! I am using a Zkteco device. I have a Zkteco Device and I have downloaded a standalone SDK, but this SDK doesn't trigger the events, (for example OnVerify, or OnAttTransaction).
  So, I read in some articles, that I need to use Push SDk, but I can't find it.</p>
