Abstract

A mobile device communicates with an authenticator affiliated with a recharging facility, to identify itself. To confirm that the mobile device is connected to the correct facility, the authenticator instructs the mobile device to draw electrical charge according to an identifiable pattern. Upon detecting a charge being drawn according to that pattern, the authenticator has confirmation that the identified device is connected to the facility, and permits the charging to proceed. The amount of electricity drawn during the charging procedure can be metered, and then billed to a party associated with the identified mobile device.

Claims
