The 日東紅茶ポイントアプリ is designed for users of the official online shop, 日東紅茶TeaMart, to accumulate points. These points can be redeemed for purchases on the platform or exchanged for various coupons. The app offers features such as daily point accumulation through scratch cards and scanning product package QR codes. Users can also earn points by participating in surveys and receive coupons as they progress through membership stages. Additionally, the app provides quick access to campaign and event information.

For utilizing points, integration with 日東紅茶TeaMart membership information is required. Users need to enable push notifications for news and coupons, and ensure their device's camera function is enabled for scanning QR codes. It's important to position the QR code correctly within the screen for successful scanning.
