Data can be transferred using ultrasonic frequencies,

Legit Uses -

Google Tone Google Tez

Bad Thing -

It has been used in the past for malicious activity by governments (if you know, you know).

I can be used to track people, like people's devices screaming their ID and devices receiving other devices IDs.

Imagine a mall with ultrasonic beacons, and for iOS and Google Play Services, hear that.
