<P>PROBLEM TO BE SOLVED: To provide a system, which generates flow line information of a vehicle moving around in a facility. <P>SOLUTION: The system comprises a wireless ID tag 3a and a wireless ID tag 3b, which are attached to a shopping basket or a shopping cart, transmit identifying information for the tags corresponding to the wireless ID tags 3a and 3b, and also transmit the identifying information for antennae corresponding to pairs of antennae (22a, 22b) and antennae (23a, 23b) responding to a radio wave transmitted by the antennae 22a and 23a for a trigger gate when the wireless ID tags 3a and 3b pass through each pair of the antenna (22a, 22b) and the antenna (23a, 23b). These identifying information for the wireless tags and the antennae are received by the antennae 22b and 23b for accepting the radio wave, and are stored with a passing through time of the wireless tags in a data file 51 for storing the pass through information for the tags. Finally, a display unit 7 displays the flow line information on a layout screen for a shopping site. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
