Once you have downloaded the user database from one terminal you can upload it on other terminals.
To upload the user database you first need to plug the USB drive into the terminal.
The port is located in the bottom of the terminal.
Once this is done you can enter the terminals menu.
Once in the 'Main Menu' you need to go to the 'USB Disk' option.
Once in the 'USB Disk' menu you need to choose 'Upload User Database'
Once the screen states that its done then you can remove the USB Disk.
And then the users data will be on this terminal and if you had fingerprints / cards / pins enrolled at the other terminal they can now also clock in on this terminal.
