The アークス app has undergone a significant renewal, introducing a range of features designed to enhance the shopping experience. Key functionalities include a digital membership card that allows users to accumulate and redeem RARA points without needing to carry a physical card. The app also supports payment options for users with compatible cards, streamlining the checkout process at participating stores.

Additionally, the app provides users with access to valuable coupons and promotional information. By registering their preferred stores, users can view the latest flyers directly within the app. The ability to check RARA point history and manage prepaid card balances further adds to the convenience, making the アークス app a comprehensive tool for shoppers affiliated with various partner stores in the region.
