Ultrasonic Cross-Device Tracking and LISNR Technology
The technology company LISNR has developed "Smart Tones," which are ultrasonic sounds inaudible to humans but detectable by mobile phone microphones. These tones can be embedded in television commercials, stadium PA systems, or web pages to track user behavior across devices without requiring Bluetooth or Wi-Fi. Intel Capital has invested in the technology, which is being integrated into various apps for proximity-based marketing and audience synchronization.
