Contactless Authentication. LISNR's ultrasonic data-over-sound technology enables contactless transactions for merchants, financial service providers and mobility companies.
LISNR is the leading data-over-audio technology that utilizes sound and software to transmit data.
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.
