SYSTEM AND METHOD FOR AUDIO SIGNAL MEDIATED INTERACTIONS

Tokens are assigned to data to be processed. Each token is associated with a unique sound waveform defined by at least two contemporaneous tones of different frequency. The waveforms can be emitted as sound at computing devices having speakers. Other computing devices have microphones and capture emitted sound to extract tokens from the waveforms. Extracted tokens can be taken as confirmation that the data is to be processed. Data can represent transactions.
