ToneTag is a company which uses encrypted sound waves to make offline, proximity-based contactless payments on any device. The company uses proprietary Software Development Kit (SDK) that encodes data into sounds. These sounds are transmitted over air and can enable payments over the existing payments infrastructure.


ToneTag was established in September 2013 by founder and current CEO Kumar Abhishek. Together with co-founder Vivek Singh they started a research project on how to enable small payments through the mobile. [1] The research was followed by experimentation with various alternate payment technologies. In September 2017, Infosys partnered with ToneTag to enable contactless payments applications. [2] [3]

WaveNet Deep neural network for generating raw audio

WaveNet is a deep neural network for generating raw audio. It was created by researchers at London-based artificial intelligence firm DeepMind. The technique, outlined in a paper in September 2016, is able to generate relatively realistic-sounding human-like voices by directly modelling waveforms using a neural network method trained with recordings of real speech. Tests with US English and Mandarin reportedly showed that the system outperforms Google's best existing text-to-speech (TTS) systems, although as of 2016 its text-to-speech synthesis still was less convincing than actual human speech. WaveNet's ability to generate raw waveforms means that it can model any kind of audio, including music.
