Smart Cash Tray for Mobile Payment

a mobile payment has attracted attention because of a consumption tax returns or measures against COVID-19. However, hurdles for those who are not used to using a mobile payment, especially for the elderly, in using the method is high. The reason for this is that they concern about using it since an exchanging of money is unseen. Therefore, we developed Smart Cash Tray that enables a virtual exchange of money in a mobile payment. We developed a prototype system that enables three dimensional displays of payment amounts with Pepper's ghost. We are trying to use ECHONET Lite for practical use.
