On June 5th, Japanese e-commerce giant Lotte announced that it would cooperate with Japan's largest railway company, JR East, to promote cashless payments. Rakuten President Nakamura said after the announcement that the current payment source of the project mainly includes credit cards, bank accounts, points, etc., but will consider the possibility of cryptocurrency payment. For the proposal to add crypto-payments, Nakamura has proposed two points that need attention, first of all, to comply with laws and regulations, and to create safe services within an appropriate regulatory framework. This is the most important. The other is not to do services that make users feel difficult.
