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

The SonoBeacon technology generates a unique high-frequency signal ...

... which is transmitted via the SonoBeacon hardware or by using an existing audio source.

The SonoApp or your extended App with our SonoBeacon technology...

... recognises the high-frequency signal and triggers the relevant customer experience.

Safety and compatibility of ultrasound signals

SonoBeacon only uses frequencies above 20 kHz - these are inaudible to the human ear.

The frequency range in which conversations take place is cut off and thus explicitly ignored.

With up to 65 decibels, the audio signals for humans and animals are harmless - every espresso machine is louder!
