Abstract: The present invention relates to a field of communication technology that provides a method, system and device of location authentication. The method comprises the following steps: the mobile device receives the signal marking the position information of the location base station sent by the location base station within the same region. The mobile device would obtain the position information of the location base station after analyzing the signal; the location base station would send the position information to the location authentication server to obtain the location authentication that it is in the same region with the location base station. Thus, this invention performs the location authentication of the mobile device staying in the same region with the location base station.

Abstract: A method for implementing electronic promotional offers and a promotion system are provided. In an embodiment, the method includes receiving promotional offer information associated with a consumer. Optionally the information may be transmitted by a near-field communication and/or in another form of two-way communication mode. The promotional offer information is authenticated. In one embodiment, the promotional offer information is encrypted during transmission and decrypted upon receipt. A request to confirm that the consumer wishes to redeem the promotional offer may be sent. After receiving the confirmation, the promotional offer information is processed and the promotion of the promotional offer is implemented.

Abstract: A stamp issuing method and a stamp issuing system are provided. In an embodiment, the method includes the following steps. Stamp information is generated by a stamp issuing terminal based on (1) consumption information transmitted from a retail terminal and (2) a predetermined stamp issuing rule. The stamp information is sent to a mobile terminal. The stamp information and account information of the mobile terminal is sent to a server from the stamp issuing terminal. The mobile terminal is associated with a user account. If the authentication is successful, the stamp information is stored, by the mobile terminal, in the user account associated with the mobile terminal. The stamp information is stored and updated, by the server, in a user account that corresponds to the mobile terminal. Using this method, at least one embodiment can send a stamp to the mobile terminal, via the stamp issuing terminal.

Abstract: A method and smart media system implementation, is provided, which includes the following steps. Setting one or more media devices to show a piece of media information. The media devices are managed by a server. A mobile terminal sets the one or more neighboring media devices as the media devices associated with the mobile terminal. The mobile terminal sends information and requests for receiving detailed media information of the associated media device to the server. The server searches the detailed media information related to the associated media device, and sends the detailed media information to the mobile terminal. As a result, consumers are provided with the effective media information according to their preferences. Also, the cost of sending information to consumers is lower than other methods.

Abstract: A method and system for offering reward options to consumers is disclosed. Offering of the reward options is triggered when a consumer visits certain locations. A server of the system is able to obtain the position of the mobile terminal of the consumer, and to determine if the mobile terminal is in the vicinity of any such location. If so, the server is triggered to offer a reward to the mobile terminal. The server stores records of visits to such locations. Alternatively, or additionally, the server stores records of reward options which have been accepted via the mobile terminal, and provides at least one selectable reward to the mobile terminal according to an updated visit record and/or reward acceptance record.
