Systems and methods for wirelessly modifying detection characteristics of portable devices

An article of manufacture comprising computer readable instructions that, when executed, cause at least one processor of a portable device to at least:

• cause radio circuitry of the portable device to scan for radio frequency beacons;
• trigger activation of audio monitoring via a microphone of the portable device in response to establishment of a first connection with a first radio frequency beacon, the audio monitoring to at least one of detect an audio code or generate an audio signature;
• and
• cause the audio monitoring to stop in response to establishment of a second connection with a second radio frequency beacon different from the first radio frequency beacon.

A method comprising:

• scanning for radio frequency beacons with radio circuitry of a portable device;
• triggering, by executing an instruction with at least one processor, activation of audio monitoring via a microphone of the portable device in response to establishing a first connection with a first radio frequency beacon, the audio monitoring including at least one of detecting an audio code or generating an audio signature;
• and
• stopping, by executing an instruction with the at least one processor, the audio monitoring in response to establishing a second connection with a second radio frequency beacon different from the first radio frequency beacon.
