Radio frequency identity (RFID) chip electrically and communicatively coupled to motherboard of mobile communication device
First Claim
1. A mobile communication device, comprising:
- a motherboard comprising a communication bus;
a cellular radio frequency transceiver communicatively coupled to the communication bus;
an antenna coupled to the cellular radio frequency transceiver;
a processor connected to the communication bus; and
a radio frequency identity chip that comprises a non-transitory memory and is communicatively coupled to the communication bus via one or more write lines having at least an electrical or mechanical cutout interposed between at least a portion of the non-transitory memory and the communication bus, wherein the radio frequency identity chip is configured to provide wireless read access to the non-transitory memory, and is configured to provide the communication bus with write access to the non-transitory memory.

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.
