20140249907 | METHOD TO RAISE ACCURACY OF TARGETING THE SEGMENTATION FOR SAMPLE DISTRIBUTION - There is provided a center server and a store terminal to enhance the targeting accuracy in providing services. The center server gives a unique ID to a member application, sends it to a particular mobile information terminal and manages it as authentication information about a member who is the user of the mobile information terminal. In response to purchases of a particular article by the member, the store terminal inputs the ID from the mobile information terminal and inputs purchase information about the article the member purchases. The center server then acquires attribute information about a member identified by the ID. Then, by checking the purchase information, the attribute information and service information set in association with attribute information about the member and kinds of articles and stored in particular storage means, information about a service to be provided for the member is identified. | 09-04-2014 |
