QIRAアプリ　大丸松坂屋カード is the official app of the Daimaru Matsuzakaya Card. The app allows users to check their QIRA［キラ］points, Daimaru Matsuzakaya points, payment amounts, and campaign information. As of January 16, 2021, the Daimaru Matsuzakaya Card has been reborn as a card that earns two types of points: Daimaru Matsuzakaya points and the newly created QIRA［キラ］points.

The app offers several useful features, including the ability to view QIRA points, Daimaru Matsuzakaya points, and payment amounts on the app's home screen. The "Auto Login" feature makes it easy for users to log in on subsequent visits. In addition, users can access the "Card Member Online Service" to view their usage details and the "QIRA Points Site" to transfer or exchange QIRA points.
