Abstract
Cashless is mentioned in the Growth Strategy for the future 2018 over and over. It has been changing from credit cards and e-money to using smartphones, cryptocurrency and so on. In recent years, it has become popular to settle with QR code in China. However, in Japan, big innovation of cashless didn't happen yet. As there are NFC readers for e-money at almost all store in Japan, it might be possible to pay with cryptocurrency. Actually, settlement with NFC and cryptocurrency has more advantages than that of QR code. Considering benefits and barriers to introduce new system, this paper shows feasibility of cryptocurrency settlement at stores by taking advantage of already maintained infrastructure.
