摘要

PROBLEM TO BE SOLVED: To provide an information gathering method capable of reducing costs required for gathering information. SOLUTION: At the time of recognizing a telephone number by calling from a mobile station or a terminal, a registration center 13 reproduces a prescribed voice message and urges a user to input a card number. In the registration center 13, the card numbers and usable points of respective prepaid cards are recorded in a data base 15 beforehand. When the user inputs the card number by a key operation or the like, the registration center 13 stores the telephone number of the mobile station or the terminal and the card number in the data base 15 by relating them to each other. The registration center 13 accesses a questionnaire center 16 and executes a questionnaire to the user. Then, at the time of receiving the answer of the questionnaire from the user, the registration center 13 makes the usable points correspond to the telephone number of the mobile station or the terminal and stores it in the data base 15.
