Although there is a variety of payment methods available besides cash in the world such as credit card, electronic money, debit card, QR code, or remittance via software application, cash payment still remains dominant in Japan.

Thus, we conducted interviews with 10 people in the present study and then analyzed the results on the basis of the Grounded Theory Approach. As a result, it was clarified that people might possibly have a certain way of process for decision of payment method, 4 conceptual categories of payment, and behavioral principle of payment. Finally, we proposed new design for a payment method to develop cashless society.
