Abstract

To realize charging while in non-contact processing operation for the purpose other than charging. An approach of a portable electronic device 2 with a rapid bulk electricity storing module 20, which is a chargeable power source, is detected at the side of a power transmitting device 1, and power transmission for charging the rapid bulk electricity storing module 20 is executed in response to the detection of the approach. A power source can be charged in operation for non-contact authentication which is executed when a device approaches an authentication device.

Claims

1-10. -10. (canceled)

11. An authentication/billing proxy device comprising:

authenticating means for executing authentication by exchanging data with a power receiving device having a chargeable power source for a user of the power receiving device;

wherein said authenticating means issues authentication information to eliminate the next authentication when the authentication normally ends, for rapid authentication which is authentication by using the authentication information.

12. The authentication/billing proxy device according to claim 11, further comprising billing means for executing billing according to the amount of charging said power source when said authenticating means authenticated the user.

14. The authentication/billing proxy device according to claim 12, wherein

said billing means executes billing according to at least one of the settings of the number of charging, a charging time, and a fixed amount of money without regard for an amount of charging, instead of executing billing according to the amount of charging said power source.

15. The authentication/billing proxy device according to claim 12, wherein

said billing means executes billing according to one of the amount of charging that is notified from said power receiving device and the amount of charging that is notified from the device that transmitted power to said power source.

13. An authentication/billing proxy device comprising:

authenticating means for executing authentication by exchanging data with a power receiving device having a chargeable power source for a user of the power receiving device; and

billing means for executing billing according to the amount of charging said power source when said authenticating means authenticated the user.

16. An electrical charging system comprising:

a power transmitting device comprising;

detecting means for detecting an approach of a power receiving device with a chargeable power source; and

charging control means for transmitting power for charging said power source, in response to detecting the approach of said power receiving device by said detecting means; and

an authentication/billing proxy device comprising;

billing means for executing billing according to the amount of charging a chargeable power source provided for said receiving device.

17-18. -18. (canceled)

19. An electrical charging method comprising:

a detecting step of detecting an approach of a power receiving device with a chargeable power source;

a charging control step of transmitting power for charging said power source, in response to detecting the approach of said power receiving device at said detecting step; and

a billing step of executing billing according to the amount of charging of said power source;

wherein said power source is charged in non-contact processing for the purpose other than charging.
