INAUDIBLE VOICE PAYMENT

Abstract:

A method and a system are provided for secure payment card transactions using a voice enabled device. The user device encodes a tokenized payment card transaction into an inaudible soundwave and emits the soundwave via a speaker to the voice enabled device. The voice enabled device, while in a listening state, detects the inaudible soundwave via a microphone. The voice enabled device decrypts the inaudible soundwave and transmits the decrypted tokenized payment for downstream processing by the payment card system.
