Abstract: Network devices, methods, and programs identify similar subjects based on physiological characteristics to predict income and expense trends. The devices, methods, and programs receive a user profile from a user terminal via a network interface, the user profile identifying physiological characteristics of the user and an age of the user, and compare the physiological characteristics of the received user profile with physiological characteristics in stored subject profiles to identify a subject having similar physiological characteristics to the user. The devices, methods, and programs analyze expense information that is associated with the identified subject to determine a trend of the expense of the identified subject, and generate a proposal including a predicted future expense trend for the user based on the determined trend and the user's age. The devices, methods, and programs then transmit the generated proposal to the user terminal via the network interface.

Abstract: At a mobile information processing terminal, a close-range communication unit performs close-range communications with another mobile information processing terminal, a reception unit receives through the close-range communication unit a user identifier for uniquely identifying a user of an application for a social networking service (SNS) on the other mobile information processing terminal, a determination unit is configured to determine whether there is a match between the social networking service on the other mobile information processing terminal and an SNS used on the mobile information processing terminal, and when the determination unit determines that there is a match, the transmission unit transmits the received user identifier to a server of the SNS so as to register a user identified by the user identifier as a friend.

Abstract: In a display device 11, a receiving unit 20 receives delivered information including an advertisement of a product and code information to be provided to a store of an advertiser advertising the product to receive an incentive reward, a display unit 21 displays the advertisement included in the received delivered information, and a short-distance communication unit 22 readably provides the code information included in the received delivered information. A portable terminal device 12 reads the provided code information via a short-distance communication unit 53 that can read and write code information. In a store device 13 receives the code information using a short-distance communication unit 81 and offers an incentive reward when the code information is received.

Abstract: Distribution information is stored in an information processing apparatus and includes benefit information. A coupon identifier (ID), which identifies the benefit information, is stored in a memory disposed within an information processing terminal. A request for the coupon ID is transmitted from the information processing apparatus to the information processing terminal and is received at the information processing terminal. The coupon ID is read from the memory disposed within the information processing terminal based on the received request, is transmitted from the information processing terminal to the information processing apparatus, and is received at the information processing apparatus.
