A proximity boundary can be defined with dimensions defined, in part, by a communication range of one of a first Short Range Communication (SRC) device and a second SRC device. A security permission can be provided to enable selected data to be communicated from one or more of the first SRC device or the second SRC device. The selected data can be communicated from one or more of the first SRC device or the second SRC device using a radio frequency (RF) communication standard. An RF link can be established between the first SRC device and the second SRC device to enable selected data communications to continue between the first SRC device and the second SRC device even after one or more of the first SRC device or the second SRC device exits the proximity boundary. ## Claims ### Claim 1 A method for proximity based communications, comprising: defining a proximity boundary with dimensions defined, in part, by a communication range of one of a first Short Range Communication (SRC) device and a second SRC device, wherein the first SRC device and the second SRC device are configured to communicate using near field magnetic induction (NFMI);
