supplying apparatus acquires communication setting information for communicating with the other communication method via the NFC, and communicates the information with the power receiving device via the other communication method according to the communication setting information. ### Claim 7 (depends on 6) The system according to claim 6, wherein the power supplying apparatus acquires the communication setting information before the position of the power receiving device transits to the second state. ### Claim 8 (depends on 6) The system according to claim 6, wherein if the power supplying apparatus does not acquire the communication setting information by the processing, the power supplying apparatus controls a wireless power suppliable area of the power supply to be narrower than that when the communication setting information is acquired. ### Claim 9 (depends on 1) The system according to claim 1, wherein the power supplying apparatus communicates billing information based on the power supply. ### Claim 10 (depends on 9) The system according to claim 9, wherein the power supplying apparatus communicates, as the billing information, a billing fee for an amount of power based on an amount of charge of the power supplying device by the power supply and power consumption of the power supplying device during the power supply. ### Claim 11 (depends on 9) The system according to claim 9, wherein the power supplying apparatus transmits the billing information including billing for the use of a billing target function to a function provided by said power supplying
