1. A method for authorizing a service, the method comprising:
- transmitting a packet having a negotiation bit to a power transmitter, wherein the negotiation bit is set to indicate that negotiation is possible;
receiving, at a power receiver within a mobile device, a packet carried via a first power signal according to an inductive wireless power transfer communications protocol; and
responsive to determining that the negotiation bit is set;
extracting a password from the received packet;
storing the extracted password in memory within the power receiver; and
transmitting the stored password in a packet via a second power signal according to the inductive wireless power transfer communications protocol to authorize the service; and
responsive to determining that the negotiation bit is not set, then the service is authorized at a reduced level;
wherein the power receiver is configured without a pathway by which a user of the mobile device can see the password stored in the memory or see the received packet.

9. A method for inductive wireless charging of a mobile device, the method comprising:
-
transmitting a packet having a negotiation bit to a power transmitter, wherein the negotiation bit is set to indicate that negotiation is possible; receiving, at a power receiver within the mobile device, a packet carried via a first power signal according to an inductive wireless power transfer communications protocol; and responsive to determining that the negotiation bit is set; extracting a password from the received packet; storing the extracted password in memory within the power receiver; transmitting the stored password in a packet via a second power signal according to the inductive wireless power transfer communications protocol; and receiving a power transfer at the power receiver of the mobile device in response to the transmitting the stored password; and responsive to determining that the negotiation bit is not set, then a reduced power transfer is received; wherein the power receiver is configured without a pathway by which a user of the mobile device can see the password stored in the memory or see the received packet. - View Dependent Claims (10, 11, 12, 13, 14, 15)
