A. 1. Educate cashiers: If possible, explain how the app works to cashiers when you use it. This can help them understand and assist you better. 2. Use printed coupons: If cashiers are unfamiliar with the app, consider using printed coupons or offers as a backup.

B. 3. Share resources: If the app has a user guide or FAQ, share that with cashiers to help them understand how to process transactions using KCL.
