In particular, when the mobile terminal 10 is in the breast pocket of the user U and the signal emitted from the mobile terminal 10 is likely to be coupled to the human body of the user (not shown) that moves forward, the possibility of such unintended charging However, since the mobile terminal 10 cannot transmit information, no charge is made.

  Next, when the user U passes between the electrodes 3 and passes over the electrodes 1, the portable terminal 10 can transmit information, and the signal including the identification information of the user U transmitted from the portable terminal 10. However, an electric field is induced in the human body of the user U and is transmitted to the control device 2 via the electrode 1. The control device 2 performs a process for debiting a certain amount from a bank account or the like corresponding to the identification information, that is, charges the user U.
