ゆうちょPay is a smartphone payment app by ゆうちょ銀行 that allows for easy payment and account balance checking. With this app, users can make payments and instantly deduct the amount from their ゆうちょ口座 (Japan Post account). The app also provides the convenience of checking the account balance in real-time. One of the key features of ゆうちょPay is the ability to set usage limits, ensuring that users do not overspend.

To use ゆうちょPay, customers simply need to inform the shop staff that they would like to pay using ゆうちょPay when making a payment at a shop displaying the ゆうちょPay mark. There are two payment methods available: customers can either display the code on their smartphone for the shop staff to read, or the shop staff can display the code for customers to read with their smartphone.

It is important to note that ゆうちょPay is a smartphone app and requires a smartphone with the necessary usage environment. Additionally, certain account types and settings are not compatible with the app. For more detailed information and guidelines, users are advised to visit the ゆうちょ銀行 website.
