To hand a guest tab over to another employee, specify the guest tab and select the Hand over command from the Change menu.

This will open a confirmation dialog:

Sign in the employee who takes over the guest tab. You can use any sign-in method: select from the list, enter the username and password, scan the ID.

After your confirmation, the selected guest tab tab will be handed over to the specified employee and deleted from the list of open guest tab of the original employee.

Pressing Cancel will close the dialog window without changing the employee who is responsible for the guest tab.
