Point system is structured marketing strategy offered by merchants to encourage consumers to continue to buy goods or pay for the services. According to the spending, merchants give consumers a certain amount of points as reward. These points can be exchanged into a good or service but not back into cash. However, as a result of the low rate of reduction, the attraction of point system to consumers is not enough, especially in the case of micropayment. This paper calls for the design of innovative technologies to provide consumers with value guidance and improve user intention, e.g., by applying gamification and AR technique. In this paper, we use mission to provide consumers with meaningful task like living a healthy life, protecting environment and promoting local economy. Point will be given if mission is completed. If completed mission reaches a certain number, the level will be upgraded. Consumer can use level information to compete with friends. If a consumer keeps completing a specific mission, he or she can get a badge. Merchant will confirm mission for consumers. In addition, we tried to use point system to solve the inconvenience caused by the small changes during the payment.
