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.
