The "Mobile WAON app" is a mobile application that allows you to use WAON with your "Osaifu Keitai" (mobile wallet). By registering for the app, you can make payments with WAON by simply touching your mobile wallet to the reader/writer, just like you would with a physical card. Additionally, you can earn WAON points or JAL miles every time you make a purchase. However, to use Mobile WAON, you need a mobile phone that is compatible with the app, and if you are under 16 years old, you need your parent's consent.

The recommended environment for using Mobile WAON is Android 4.1 or higher.
