Traditionally all cards and paper issued as cards and paper such as membership cards, custody cards, announcements, coupons, questionnaires, etc. will be collected on the smartphone.
From now on, you do not need to bring a membership card or custody card when you go to a store.
I do not have to worry about losing them.
By simply looking at the receipt form screen, you can check what you are currently depositing in the store without omission.
It is also possible to get notices and coupons from stores.
If a questionnaire is sent from a store, it is also possible to answer it.
