The key to our SonoBeacon technology developed with the Fraunhofer Institute for Secure Information Technology is the audio signal:
The audio signal is inaudible to the human ear.
The corresponding information is modulated on the audio signal.
The signal is transmitted via a sender - a loudspeaker.
The microphone of a smartphone acts as the receiver.
The complete information decryption takes place on the smartphone.
How it works
Safety and compatibility of ultrasound signals
