SOLUTION: A host device 20 collects the service points of members which are calculated by the commodity sales registration data processors 10a to 10c respectively. Then the device 20 sums up the collected service points of members for every member to calculate the latest point of them and then distributes these latest points of members to the processors 10a to 10c of the stores of the corresponding point members respectively. The processors 10a to 10c receive the latest points of members from the device 2 and adds them to the total points of the corresponding members which are stored in the member files 14.
