System and Method for Code Communication

A wireless communication device, comprising:

• one or more memories;
• a digital compass configured to sense a sequence of polarities of a short-range magnetic field;
• and
• one or more processors operatively coupled to the one or more memories, wherein the one or more processors are configured to determine a code from the sensed sequence of polarities, wherein the code provides access to a secure system, wherein the one or more processors are configured to wirelessly transmit the code received from the short-range magnetic field and identification information to the secure system to receive access to the secure system, wherein the access is personalized based on at least the identification information and is maintained or validated when the wireless communication device is within range of the short-range magnetic field.

A cellular phone, comprising:

• one or more memories;
• a digital magnetic sensor configured to sense a sequence of polarities of a short-range magnetic field;
• and
• one or more processors operatively coupled to the one or more memories, wherein the one or more processors are configured to determine a code from the sensed sequence of polarities, wherein the code provides access to a secure system, wherein the one or more processors are configured to wirelessly transmit the code received from the short-range magnetic field and identification information to the secure system to receive access to the secure system, wherein the access to the secure system is maintained or validated when the cellular phone is within range of the short-range magnetic field and is personalized based on at least the identification information.
