Hi Rahul,
There are two options to bring the data of Attendance machine to our device.
First is a manual process where you can use a pen drive to store the attendance data and then put the file in server and specify the path in Time Registration under Devices -> Mapping
Second method is to port forward firebird port 3050 at the host location itself and then in the remote location where the device is there we need to install communicator, connection manger and ITAS.CON. in the connection manger path give the db path. Also location should be matching in communicator in remote location and also in devices at head office.
The second method would require more details to implement, please contact your support executive.
