MUJI Pay is an app that allows you to make quick and cashless payments using just your smartphone without having to go through the hassle of traditional checkout lines at MUJI stores. By registering your credit card within the app, you can easily shop without the need for physical cash. Simply scan the displayed QR code at the payment terminal to complete your transaction, eliminating the need to wait in line at the cashier.

Moreover, by integrating with your MUJI passport app, you can accumulate MUJI miles as you spend (1 mile for every 1 yen spent), adding value to your shopping experience.
