Visitor appointments can be pre-booked either directly on the system or through the online Appointment Planner found within Tensor's Self Service Module (SSM). Employees with an account can log into SSM using their Internet browser. Depending upon their security profile, SSM users can view and make appointments for themselves or colleagues. SSM users can also create new visitor and visitor company entries, view their own appointments, view all appointments at their site or view all appointments for their organisation.
