Leverage smartphones, the devices closest to the end user, to drive DX (Digital Transformation) for retailers. In particular, providing a customer experience that combines online and offline (OMO: Online Merges with Offline) is expected to become the new retail standard. In the past, the customer experience was mainly limited to the in-store experience, but now, it won't be limited to just in-store, but can be highly designed as a seamless customer experience from before to after the in-store experience, providing significant benefits to the end user.

By using LIFF / LINE MINI App, you can complete all of the following value provisions with one LINE. User behavior data acquired with LINE Official Accounts and LIFF / LINE MINI apps can be stored in CRMs prepared by service providers to realize the finest and seamless customer experience customized for each end user.

  • Improve the purchasing experience through smartphone checkout, digital membership cards, and functions for checking purchase history (receipts)
