1. A method of organizing components of a mobile communication device, comprising:
- orienting a radio frequency identity (RFID) chip on the mobile communication device relative to a general purpose near field communication (NFC) transceiver on the mobile communication device, wherein the RFID chip comprises an antenna and the general purpose NFC transceiver produces an electromagnetic field that has a null region; and
locating the RFID chip on the mobile communication device such that the antenna of the RFID chip is aligned in the null region of the electromagnetic field radiated by the general purpose NFC transceiver, wherein the null region of the electromagnetic field produced by the general purpose NFC transceiver provides less than a threshold amount of power required to activate the RFID chip via the antenna.

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.

10. A mobile communication device, comprising:
-
a general purpose near field communication (NFC) transceiver configured to produce an electromagnetic field, a radio frequency identity (RFID) chip, and an electromagnetic shield that attenuates the strength of the electromagnetic field radiated by the general purpose NFC transceiver that is incident upon the RFID chip, wherein the RFID chip and the electromagnetic shield are disposed within the mobile communication device such that the RFID chip receives less than a threshold amount of power required to activate the RFID chip from the electromagnetic field produced by the general purpose NFC transceiver of the mobile communication device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
