The store corresponding to the commodity tag taken home by the customer can be identified even when the commodity tags are placed in a plurality of stores. Thereby, when a commodity is purchased from an online store or the like other than the store corresponding to the commodity tag taken home, a reward (return) can be given not only to the final purchase store but also to the store where the commodity tag is placed.
