According to MK Business News:
In particular, the North is reported to show much interest in electronic payment systems appearing in the global market. It is well known that Kim Jong-un in his early 30s, who directly experienced the information and communications revolution, has put a lot of efforts into technology development in the field of information and communications technology
“North Korea is keenly interested in electronic payment systems such as PayPal,” said Park Chan-mo (79), an honorary president, who teaches students in Pyongyang University of Science and Technology, in an interview with the Maeil Business Newspaper. He elaborated on the changing North Korean society during the three year regime of Kim Jong-un.
Of course the DPRK has already started experimenting with electronic payments in the form of the Narae and Koryo Bank debit cards. Of course, these technologies are restricted to the use of hard currency, and we are unsure of the scale of their by ordinary North Koreans (as opposed to foreigners). There was one story on this topic here. I have also see North Korean television footage advertising a prepay card used by some of the restaurants on Changwang Street just north of the Koryo Hotel.
