アークスアプリ is a lifestyle app developed by 株式会社　アークス. It serves as a substitute for a membership card, allowing users to earn points even without physically carrying their RARA card. By presenting the app's membership card barcode screen to the cashier, customers can accumulate points while shopping. Additionally, customers using RARA Prika can also make payments using the app's membership card. The app provides a convenient way to check accumulated points and usage history, as well as the ability to charge accumulated points to Prika in 500-point increments. Users can also receive leaflets and deals from their favorite stores, making shopping even more rewarding. With its store search feature, users can quickly find nearby stores or search by municipality. The アークスアプリ is a must-have for anyone looking to enhance their shopping experience.
