Abstract: Systems and methods for code communication are provided. A secure system wirelessly transmits, via a magnetic field transmitter, an access code to a handheld wireless communication device as a sequence of polarities of a short-range magnetic field. The wireless communication device senses the sequence of polarities and determines the code from the sensed sequence of polarities. The code provides access to the secure system. The handheld wireless communication device can 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. The access is personalized based on at least the identification information and is maintained or validated when the handheld wireless communication device is within range of the short-range magnetic field.
