Using sound to transmit data might sound like science fiction, but it could soon come to a Jaguar Land Rover product at a dealership in your area.

Jaguar Land Rover’s tech incubator now includes Lisnr, a company devoted to using what it calls Smart Tones to transmit data using sounds that are outside the human register for hearing. A car equipped with this technology could theoretically communicate with a number of other devices equipped with the same tech, unbeknownst to the user himself.

Using a mobile app, folks can connect to a Jaguar Land Rover vehicle equipped with Smart Tone technology. The car could then tell who is located in the vehicle, down to the seat location, and adjust vehicle settings to individual user preferences. It could detect a driver and change radio favorites, or adjust the seat or climate control so that the driver doesn’t have to, even if they weren’t the last person to use the vehicle.

The tech can be used beyond climate control adjustments, though. The sound tones could be used to replace key fobs with the phone in a user’s pocket. It could work with a drive-through to display the restaurant’s menu on the infotainment system as the driver approaches the window, or even transmit the order to the restaurant, as well.
