1. A method for unlocking and engaging a radio frequency identity chip of a mobile communication device, comprising:
- receiving a signal on the radio frequency identity (RFID) chip to unlock;
responsive to receiving the signal, unlocking the RFID chip;
responsive to unlocking the RFID chip, engaging the RFID chip with a near field communication (NFC) scanner, wherein the NFC scanner is a general purpose NFC transceiver of the mobile communication device;
transmitting a biographical digest from the RFID chip to the NFC scanner; and
subsequent to the transmission of the biographical digest, instructing, by the RFID chip, the general purpose NFC transceiver to ignore the RFID chip and locking the RFID chip.

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.
