How do I use the stamp card?
Each time you give food to your aibo™ robotic companion, your stamp card gets Yum-Yum Stamps. After collecting a specific number of Yum-Yum Stamps, you'll get bonus treats. To check how many Yum-Yum Stamps you have, tap Food on the Home screen of the My aibo app, and then select Yum-Yum Stamps.
Note: You can't choose the type of treats you get.
