<P>PROBLEM TO BE SOLVED: To manage an advertising medium with high accuracy by utilizing an IC tag. <P>SOLUTION: An advertisement management server 20 of an advertisement management system refers to distribution possibility information storage means 44 on the basis of identification information transmitted from a portable information terminal 8 and distributes advertisement related information to the portable information terminal 8 in the case where a distribution enabled state is determined but, in the case where distribution possibility information indicates a distribution disabled state, on the other hand, distributes an opening authentication request to the portable information terminal 8. Upon receiving the opening authentication request, the portable information terminal 8 transmits authentication information, thereby rewriting the distribution possibility information stored in the distribution possibility information storage means 44 inside the advertisement management server 20 into the distribution enabled state. Thus, as long as the distribution possibility information indicates the distribution disabled state, the distribution of advertisement related information to all the portable terminals 8 is prohibited but after the distribution possibility information is rewritten into the distribution enabled state, the advertisement related information can be distributed to all the portable information terminals 8. <P>COPYRIGHT: (C)2012,JPO&INPIT |
