<p><P>PROBLEM TO BE SOLVED: To provide an automatic toll collection system capable of performing charging processing without charging omission even if a driver performs illicit operation to an on-vehicle device. <P>SOLUTION: First road-to-vehicle communication is performed through a first antenna 101 (S31). An on-vehicle device ID and an IC card ID are collected (S32). The collected on-vehicle device ID and IC card ID are retained (S33). Second road-to-vehicle communication is performed through a second antenna 201 (S34). When the communication is impossible, charging specification data is formed to the IC card obtained by the first road-to-vehicle communication (S35). When the communication is possible, comparison with the on-vehicle device ID obtained by the first road-to-vehicle communication is performed (S37). Comparison with the IC card ID obtained by the first road-to-vehicle communication through the first antenna 101 is performed (S38). When the both are mismatched by this comparison, charging specification data is formed to the IC card obtained by the first road-to-vehicle communication through the first antenna 101. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
