Engagement offline at
35 thousand feet

through ultrasound

Why engage with


It is the most powerful proximity marketing tool for these reasons:

  • SOUND IS EVERYWHERE - We use inaudible ultrasonic technology as a communication protocol that sends data through audio to transmit information.
  • OFFLINE PEER TO PEER CONNECTIVITY- It works great in all the situations with zero connectivity issues, and there is no need for WiFi or Bluetooth
  • ON-DEVICE ENCONDING- It does not require a server call to decode a tone, which means it can create shopping experiences without wifi, data or general device connectivity
  • MEASUREMENT OF THE AUDIENCE- Understand your public. NFCSound signals with data can be broadcasted from any speaker, dramatically increasing the size of your audience and the richness of your audience data

After the flights have landed send them a survey or poll to check their satisfaction

Engage your passengers at the airport. You can reward the ones that come early on board or to the departing gate by broadcasting signals that the pax can listen, and once the data have been decoded they discover a prize, like free items on board!

Turn the waiting at the airport or during the flight through gamification. Let them play before and during the flight by briadcasting gamification data from the sound!

But it can also be a wide range of issues like degree of comfort, services, satisfaction, food, etc.


We create the ultrasonic signals with data that the airlines can broadcast. When the users listen to the sound source the app will detect the signals and aumatically decode the data and turn it into something useful for the user.

From any sound source, like the PA system of the aircraft, embedded in videos, publicity, from posters, gates, offices, etc. We also have our own ultrasonic beacons that broadcast the data in inaudible high frequency audio barcodes

Information, coupons, polls, surveys, links to sites and more
