A proximity boundary can be defined by a communication range of one or more SRC devices configured to communicate using near field magnetic induction (NFMI) using at least two antennas to provide magnetic induction diversity. A data block can be securely communicated by interspersing the data between an short range communication (SRC) device for near field magnetic induction (NFMI) communication within the proximity boundary and a radio frequency (RF) radio for RF communication.
