Visitor Professor Jeong Soon-chae of the Department of Computer and Communication Engineering, Dongguk University, who is a police officer, said, "It is possible to investigate by tracking the location or input of a PIN number, but it is time consuming and time consuming." "You have to have your own device that can do that."

As the Financial Supervisory Service monitors banks and securities transactions, the gift certificates are issued, distributed, and used. "We need a dedicated organization to manage the entire process transparently."
