The electric battery comprises an internal metal plate and an exterior package skin. The RFID chip is retained by the exterior package skin of the electric battery and comprises a non-transitory memory, a processor, a radio transceiver coupled to the processor, an antenna, a first impedance matching component coupling the radio transceiver to the antenna, and a second impedance matching component coupling the internal metal plate of the electric battery to the radio transceiver, wherein the radio transceiver is configured to transmit radio frequency signals through the second impedance matching component to the internal metal plate and the internal metal plate is configured to radiate the radio frequency signals as radio waves.

Abstract: A method of organizing components of a mobile communication device. The method comprises orienting a radio frequency identity chip of the mobile communication device relative to a general purpose near field communication transceiver of the mobile communication device, locating the radio frequency identity chip in a null region of an electromagnetic field radiated by the general purpose near field communication transceiver, whereby, the null region of the electromagnetic field may be below a threshold required to activate the radio frequency identity chip.

Abstract: A method of managing a lifecycle of a mobile communication device. The method comprises storing a biographical digest in a radio frequency identity chip of the mobile communication device at the time of manufacture of the communication device, wherein the biographical digest comprises information about the device and comprises a static portion and a dynamic portion. The method further comprises activating the device for wireless communication service; after activating the device, deactivating the device for wireless communication service; and after deactivating the device, writing a device status of the dynamic portion of the biographical digest in the radio frequency identity chip of the device to a value of dead, whereby the device is prevented from being activated for wireless communication service after once having the device status of the dynamic portion of the biographical digest in the radio frequency identity chip of the device written to the dead value.

Abstract: A radio frequency identity (RFID) tag. The tag comprises a processor, a memory, wherein the memory stores private information and public information, and a radio transceiver configured to receive a request for information from an RFID reader and to transmit a reply to the request for information. The tag further comprises an application stored in the memory that, when executed by the processor, parses a request for information from the RFID reader received by the radio transceiver, and determines whether the RFID reader is authorized to receive the private information. When the RFID reader is determined to be authorized, the application reads the private information from the memory and sends the private information to the radio transceiver to transmit; when the RFID reader is determined to not be authorized, the application reads the public information and sends the public information to the radio transceiver to transmit.

Abstract: A radio frequency identity (RFID) chip. The RFID chip comprises an antenna to receive and transmit information signals and to receive power radiated by a radio frequency power source, an electrical power induction component coupled to the antenna, a radio transceiver coupled to the antenna, a memory, a connector that is configured for connecting the RFID chip into a communication bus of a circuit board and to a battery derived source of power provided by the circuit board, and a processor coupled to the connector, the memory, and the radio transceiver, wherein the processor is configured to read from the memory and to provide the information read from the memory to the radio transceiver for transmitting and to read from the connector and write the information read from the connector to the memory.
