Abstract
In accordance with the present invention, an apparatus initiates a transaction and includes an acoustic data receiver, and microphone for receiving an audio signal having encoded data that is non-discernable by a listener and is transmitted as part of the audio signal. The microphone converts the sound waves into an electrical signal. A processor receives the electrical signal and retrieves transaction data that is part of the encoded data. A filter is associated with the microphone and removes a substantial portion of a human voice signal that may have been received within the microphone. Once the transaction data is retrieved, a telephone call can be originated and at least a portion of the transaction data can be transferred to a desired destination for initiating a transaction.

26. A method for receiving acoustic data comprising the steps of
receiving an audio signal within a microphone, wherein the audio signal has encoded data that is non-discernable by a listener and is transmitted as part of the audio signal, removing a substantial portion of a human voice signal that may have been received within the microphone by filtering the frequencies substantially associated with the human voice, converting the audio signal into an electrical signal, and receiving the electrical signal and performing work on the signal for further processing or data communication.
-
30. A method for initiating a transaction comprising the steps of
receiving an audio signal within a microphone of a capture device, wherein the audio signal has encoded transaction data that is non-discernable to a listener and is transmitted as part of the audio signal, removing a substantial portion of a human voice signal that may have been received within the microphone by filtering the frequencies substantially associated with the human voice, converting the audio signal into an electrical signal, processing the electrical signal to retrieve transaction data that is part of the audio signal, and originating a telephone call and transferring at least a portion of the transaction data to a desired destination for initiating a transaction.
