Point system is the most common loyalty program methodology. Frequent customers earn points, which can be used to redeem for money off in next purchase. Customers work toward a certain amount of points to redeem their reward. However, current point system is not enough to guide reasonable consumption. In this paper, a gamified point system is put forward. Points are divided into different categories based on source.We introduce mission into point system. Mission content is designed to guide consumption. In our system, point, mission and virtual pet will be spatially visualized using AR technique. The state of virtual pet depends on the evaluation for users. Users need to adjust themselves to keep their pets in a good state.
