A method and a system are provided for secure authorization of credentials using a voice enabled device. The user device encodes encrypted authorization credentials 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 decodes the inaudible soundwave and transmits the cryptographically secured authorization information by the payment card system.
