It is also commonly called portrait recognition or facial recognition. Traditional power system services require customers to go to the business hall to consult staff and queue up at the counter, which takes a long time and has complicated procedures. At present, power terminal devices have been used in business halls, and customers can handle related services on the terminal devices, which greatly improves the speed at which customers handle business.
