Abstract (in Japanese) (See Japanese page) 
(in English) We made a survey of the technology trends on Payment System using Virtual Currency and Electronic Money based on patent applications and journal articles. We read domestic and international 24,000 patent documents and 6,000 journal articles. Then we classified them based on the type of the payment system method and the technological problem. We report on the result of the survey.
