LINE API Use Case

Easy-to-issue membership cards

You can use the LIFF app to provide membership cards for your own services on LINE.

For example, companies that provide membership cards at offline stores, such as supermarkets, drugstores, and apparel stores, can also shift to online membership cards. If the conditions are met, it's possible to build a communication channel with users that can't be achieved with physical membership cards alone. Specifically, you can use the user ID obtained with the LIFF app to send push messages such as sales promotions.

Membership cards can be issued immediately without entering any personal information

Generally, when issuing a membership card, personal information such as name and address is required to identify the individual. However, online membership cards using the LIFF app can be linked to the user's registered information on LINE. In other words, since there is no need to receive personal information from users, membership cards can be issued without incurring unnecessary costs and preventing leakage of personal information.
