OnlineSDK is not provided by the manufactures, hence we cant find anywhere. We can integrate the biometric machines with the remote server in only two ways:
1. With the help of SDK, develop a windows application, which will read the attendance data from the biometric machine which has been connected into the local network, and push the data to your server instantly.
2. Find Web API supported biometric machines and connect the machines to your remote server directly　TEst.
