We use near-ultrasonic sound to transmit data using a speaker to and between any smart device with a microphone. A device enabled with LISNR® software can detect, transmit, and receive data from LISNR® audio technology within audio range. Once a LISNR® signal is detected, the SDK demodulates the data sent over the audio and performs the specified function on the device based on the data.
LISNR's ultrasonic platform consists of 3 core product optimizations - close range data transmissions called "Point", mid range transmissions called "Zone" and long range transmissions called “Radius”. We’ve optimized our platform offerings around these key products & use cases.
Get your free Mobile Apps report, a PYMNTS and LISNR collaboration analyzes survey data collected from 1,045 American consumers to learn how they use merchant apps to enhance in-store shopping experiences, and their interest in downloading more in the future. Our research covered consumers’ usage of in-app features like loyalty and rewards offerings and in-store navigation, helping to assess how merchants can design apps to distinguish themselves from competitors.
