The "札幌市店舗用アプリ" is designed exclusively for participating stores of the "Sapporo Life Support Premium Voucher" program. Users can access various features such as sales confirmation, payment history review and search, instant payment cancellation (for user refunds), and progress tracking and history of settlements.

Additionally, the app supports handling paper vouchers with QR codes. Store staff can scan the QR code printed on the paper voucher presented by the user, input the purchase amount, and proceed with the payment.

To utilize the app, participating stores need to register first by following these steps: download the app, log in using the account information provided in the starter kit, and access the various functionalities available upon login.
