Offline through ultrasound

Create sound-geofencing zones in your hotel


                       Divide the areas of engagement in your hotel and decide how you want to connect with your guests.
                       By broadcasting the engagement data through the sound, your guests can receive relevant information of the area where
                       they are located totally offline and without needing any internet connection.
                       Some examples of geofencing transmission zones:

Hotel information, types of rooms and prices, facilities and features

A map, opening times of the facilities, fidelity program, tours, excursions

Safety information, emergency exits

Menu, prices, recommendations, meal times

Safety information, schedules, services, drinks menu

Safety, services, bar menu, orders, schedules

Engage offline with ultrasound

  1. CREATE- Your campaign and how you want to engage your audience, with deals, notifications, tickets, announcements, votes, rewards, etc. and the relevant message that you want to transmit
  2. SIGNALS- When you have decided how to engage your fans, we will create the ultrasound signals with data that will be integrated into the sound of the music, speaker or our ultrasonic beacons
  3. ENGAGE- When the app decodes the ultrasonic data it executes the chosen action, such as registering in the event, voting, or any other action
  4. ANALYTICS- At the end of the campaign you will measure and understand better the behavior of your audience, reward their loyalty and serve them better
