For collecting market research data and promoting business activities in a selected geographic area, user information containing users' profile and preference information is received from a mobile terminal and a user identifier is assigned to the user of the mobile terminal, The assigned user identifier is mapped to the received user information in a first database, and the assigned user identifier is transmitted to the mobile terminal. A user identifier, when received from a mobile terminal, is checked for verification. If the received user identifier is verified, the user of this mobile terminal is allowed to transmit area-specific information that can obtained only when the user is in the selected geographic area. Corresponding to the verified user identifier, user information in the first database is detected and mapped to the received area-specific information in a second database.
